Now that I think about it, that'd be a good idea. I don't want to step on the Spell of Clear Thought's toes too much, but smaller amounts of Research probably wouldn't hurt.
Cursed Coronet will be a tricky option to use in the Tower; it's strong for Challengers, but Tower Lords will be rough. I'd run it with the Aeric Raiment so that you can cap the debuff at 50%. (Maybe I could make it so Check doesn't tick down the Cursed Coronet debuff...)
