No, there is no possible checkmate with 2 (or more) same-coloured bishops against a bare king. The game is drawn immediately.

If you add a Black pawn, a checkmate pattern become possible. However, it takes 5 bishops (!) in [this][1] study (by S.Loyd, I think) for White to be able to force a checkmate !
