TLDR; No, spell "stacking" isn't covered in
Hero Quest, though it might be inferred though other cases of exceptions found within the Instruction Book, Armory, expansions, and cards. First off is the case already brought up:

We already know that “one extra dice” doesn’t stack for equipment. IE you can’t wear two helmets. Or have on two chainmail. If you cast a spell once, the hero would get the benefit, and if was cast it again they would just “overwrite” the spell. And you’re still only getting “one extra dice...”
Yes, bonus dice do not stack with the same armor type. And as Kurgan later pointed out, two Shields is a possible exception. The Wizard's armor prohibitions indicate the difference: "May not be
worn by the Wizard."--Helmet, Chain Mail and Plate Mail/ "May not be
used by the Wizard."--Shield.
The common-sense logic is that the same armor cannot be stacked physically when worn, so the extra dice don't stack either. The Shield remains a possible (but generally impractical) exception because of the different action implied by
used. A Shield can be used in one hand, so two can be used in each hand for two stacked Defend Dice.
There is a more practical case of dice that don't stack, but with a specified exception for attacking. The Instruction Booklet allows a
Hero to make separate defense rolls for separate attacks from multiple monsters in a turn. So Zargon can't add 3AD + 3AD = 6AD from two attacking Orcs.
The exception to attacks is found in an expansion, the Barbarian Quest Pack. A Polar Warbear has two attacks which effectively stack since the defending
Hero may only defend once against both of it's attacks. In other words, 4AD + 4AD = 8AD.

They can’t (in dragon ball style) “super-Shapeshift”. They’re not casting “Shapeshift Bear” and “Shapeshift Tiger”. (Which in my opinion might be able to stack.)
They’re casting the exact same spell. They still are only affected by the spell “Shapeshift”. As long as they’re affected by that spell they would get the one additional attack and defense dice. . . .
The key term causing uncertainty in my opinion is ". . . one
extra attack. . . ."

adjective
1 beyond or more than what is usual, expected, or necessary; additional
I'd say ". . . more than what is usual, expected. . ." has a separate sense in HQ from ". . . additional." The first sense of "extra" doesn’t allow spell stacking because going beyond what is usual--the
druid's standard AD and DD before the spell--is a one-time change to an unusual, modified state (+1AD, +1DD.) The
Druid's scores are no longer usual while under the effects of the Shape-Shift spell, so it cannot be cast again until the spell effect is first lost, returning the scores to the usual state.
However, I think the second sense (additional) does work with stacking. The starting
Druid with 3 BP casts Shapehift once (1+1 AD and 2+1 DD.) She next has her BPs restored, regaining the spell. Later, she casts the spell again, granting her one extra (additional) AD and DD (2+1 AD, 3+1 DD.) The effect of the spell in this interpretation is a simple math operation done twice.
Based
on Doug Hopkin's stated intention to keep a shapeshifted
Druid on par with the Barbarian, he apparently doesn't expect Shapeshift to stack. However, were I one of his play-testers, I'd point to how stacking was handled in the Kellar's Keep and Return of the Witch Lord.
In the Alchemist's Shop, the Potion of Dexterity adds 5 movement squares--but no more--as the text specifies only one of these potions may be used by a
Hero per turn should he buy more. This is clearly an exception to prevent stacking of the same bonus effect. Since an exception exists, it follows that other potions without such explicit restrictions may be drunk more than once in a turn, as per the no-limit rule for potions found
on p.17 of the Instruction Booklet. So a
Hero could drink two Potions of Defense and gain 2 extra DD +2 extra DD = 4 extra DD for one turn.
Others may disagree, but I judge it reasonable that the concept of permitted stacking of potion bonuses anagolously applies to any spell card as long as a restriction isn't explicitly included in the text (
see here.) For instance, if it is possible to recast Rock Skin either through the use of a Potion of Magical Aptitude, the Spell Ring, or a Spell Scroll, then a
Hero could gain the bonus twice (1 extra DD +1 extra DD = 2 extra DD.) The downside is once any BP damage is suffered, all extra DD are lost at once as the end conditions of both spells are met simultaneously.
As for Shapeshift as currently worded, the spell is at least absolutely limited to +2 AD, +2 DD (one stack.). The
Druid is set to do this twice a Quest. Eventually while double-shapeshifted, that's either 6 AD/ 4DD (Battle Axe) or 5 AD/ 5DD (Longsword and Shield.) A Barbarian will likely have either 4AD/ 4 or 5DD, or 3AD/ 5 or 6DD. As I said earlier in this thread, I'd hope Avalon Hill playtesting reveals if playing Shapeshift this way is overpowered, considering the
Druid is usually combat-compromised.
