You don't understand how the eap2 module works.

There is not much code in eap2; eap2 just passes all the EAP requests to 
the codebase in hostapd.

You can't just "move" EAP-AKA from the eap2 module to eap, because there 
isn't actually any EAP-AKA code there - it's all in hostapd, which is a 
completely different codebase with a different API, different coding 
conventions, different build infrastructure, etc.

If you want EAP-AKA support in the main "eap" module, you'll have to 
write it, or pay someone to write it, from scratch. I guess the EAP-AKA 
code in eap2/hostapd could be used as a reference, but that's about it.
