IANAL/IANYL. Make it dual-licensed, AGPL with MIT by request. Indicate that you are presently declining MIT license requests. The chances of your agreement being adhered to are near zero, regardless of the legality. On the other hand, any mention of GPL will send lawyers running for the hills - AGPL more-so (and legally so, it makes your code basically useless to a corp). The MIT carveout is merely there so that contributors don't throw a fit if you choose a more permissive license down the line.
