From my Twitter feed alone came these suggestions for the Oscar host to replace the now-exiting Eddie Murphy:
--Neil Patrick Harris
--Ron Swanson (aka Nick Offerman)
--Old Hoss Radbourn
--Troy and Abed from "Community" (Danny Pudi and Donald Glover)
--Amy Poehler and Tina Fey
--Roman Polanski and Mel Gibson
Based on the interest, I have suggested a 12-week reality show in which the finalists compete for the gig.
