If you're asking if you can manually re-bind all of the view bindings 
to use one controller, then yes, that will work fine. I don't know of 
any way to "consolidate" the bindings short of doing it manually, one-
at-a-time, though.

Not necessarily. You may want more than one controller for an entity 
if, for example, you want to use different filter predicates in 
different views. IB has no idea what you might get up to, so it 
creates the most conservative case -- a different controller for each 
view.
