Michael Rome at BloodyElbow had an interesting piece about bringing the 135 and 145 divisions of the WEC over to the UFC but keeping the WEC alive as a Development league for the UFC.
Link That would keep both the UFC's TV deals in place, it would keep all or atleast most of the WEC's staff employed. It would improve the UFC's roster and options for headlining fights while also giving 135 and 145 lb fighters an opportunity to be paid like their heavier counterparts.
Like he said in the article,
"There's no reason a company like Bellator should be grabbing prospects like Ben Askren while the UFC can't even find proper prospects for its reality show."
