so, kinda but no. EAP is a layer 2 authentication that uses encryption as well.
WebAuth is a layer3 authentication only.
Now the kinda....you can create guest/network users on the WLC local database, and if someone logins to the webauth portal with those credentials they will be able to get on.
I'm not really sure what you are looking to do based on your post.
Personally, if I had users that were going to roam to this controller, I'd work with that companies IT and get it linked to my AAA server and keep the EAP-TLS that I had working already going. Just because that WLC would be able to communicate to your AAA doesn't mean their users would be able to get on, as they wouldn't have the machine or client certificate nor the Root CA cert on their machines.
