Yes.  I've done the opposite without much grief but we still called a 
it flag day and did everything in one maintenance window.

Yes....    But keep in mind that EIGRP carries with it an administrative 
distance of only '5' whereas OSPF is at 110.    You might consider moving
the adminstrative distance for EIGRP to something above OSPF across 
your network until everyhting is in both routing processes. Then kill off 
OSFP and move AD back to it's default values.
