I really like this idea 
I think it was stated that Superman would be the strongest lantern once due to his powers plus the lantern powerrs(though I could be wrong)

Kara was strong enough to remove the red ring without dieing, so I'm sure he's strong enough to do at least that.

Edit: I thought of a way to arrange the RP.  What if I had two topics, one for the DC universe and one for the Marvel?  Each would have their own arc.

Edit2: I fixed the rings in the OP.  Does anyone have any changes they want me to make before I launch the OOC topics?
