Permanency and Enlarge person.

[Malik Gyan Daumantas]

So i actually got this crazy idea that im not sure would work
In fact im like 75% sure this won't work but...
Can you get enlarge person cast on you permanantly and then use the abyssal bloodrager Demonic bulk ability to go huge?

Size change FAQ wrote:

As per the rules on size changes, size changes do not stack, so if you have multiple size changing effects (for instance an effect that increases your size by one step and another that increases your size by two steps), only the largest applies. The same is true of effective size increases (which includes “deal damage as if they were one size category larger than they actually are,” “your damage die type increases by one step,” and similar language). They don’t stack with each other, just take the biggest one. However, you can have one of each and they do work together (for example, enlarge person increasing your actual size to Large and a bashing shield increasing your shield’s effective size by two steps, for a total of 2d6 damage).

No, they won't stack.

Enlarge Person clearly states it does not stack.
