MAC Awards in 2 Stages - Initial Proposals and FPRs

I?ve been bouncing this one around the office and have gotten some funny looks, though it seems perfectly logical to me. Here?s the hypothetical: We have a procurement to solicit and award a 16.5 MAC with, say, 6 contracts. The RFP states the Government will evaluate proposals and award contracts without discussions. After evaluations, if we find only 3 proposals awardable without discussions (no signicant flaws, otherwise very good proposals), do you see a problem with awarding these 3 immediately, then setting a competitive range and entering discussions with the most highly rated proposals determined from the remaining offers? Assume we announced our intent to take this approach in the RFP.
