Well, they are implementing "spell crafting" which allows you to merge 2 spells to create an entirely new one, but from what I've seen, the resulting spell will belong to a specific school of magic. I actually think it'd be cool if by crafting a "fire" and "earth" spell together, you would create a spell that actually belongs to both the fire and earth skills and requires that you put skill points in both. They could do the same thing with the non-magical skills.
The idea being that by putting stats into 2 different areas, you aren't "multiclassing" but rather you're creating an entirely new class.
I think that would be cool.
