NFO's are marginally cheaper to train and should be cheaper to advance through their fleet quals and keep current. Having said that, "cheaper" really is a relative term. In the long term the personnel costs become the dominant driver. The Brits have done it with no issues, but I would think Navy politics would really drive this. The NFO community would obviously want more opportunities I would think, and the HSL/HSM manning model has a lot of problems, but there isn't any inherent support in the community for it (and I don't see where their SWO allies would care).
Personally, I don't see anybody who matters being willing to spend money now in order to gain those relatively small long term gains, especially when you factor in that large chunks of the Romeo mission set can be performed as well or better by a UAS (or whatever abbreviation I'm supposed to be using for those).
