Is it possible to take a stock AC30 and put Blue Alnicos in it?
As long as the wattage, size and Ohms all match, yes.

EDIT: The wattage doesn't have to match - it just has to be near to the number the amp puts out. i.e. it can be a little less, or it can be more, much more.

The Epiphone Valve Junior, for instance, is a 5w amp, but its speaker can handle 75w of power.

Greg what did you send me??
I would Imagine it would work, I think the only thing you would need to watch out for would be that A, the speaker actually fits, cause that would be a bitch to modify, and B, that the ohms match.
