Sorcery and Alternate Form

[CarrionPeacock]

It was discussed in another internet forum the possibility of using Sorcery and Alternate Form to simulate Persona from the game series of the same name.
The idea is that the base character would purchase Sorcery Empowerment and multiple Alternate Form, each granting a sorcery spell set to be used. What's the right way of doing it?

The way it was suggested, the Alternate Form itself wouldn't be a spell, but the spells it grants would naturally be. For example, one form would cost 15 points normally and contain 5 spells, each with full cost of 20 points, divided by 5 because it is a spell, making it cost 4 points each, total 35 point for the first form, plus 15 for each additional one. Is it legal? I feel like there's a nesting problem but I can't say for sure.
