My midlength with aid could is a pretty soft shooter. I think you'll have to go pretty large relatively. I'm thinking you'll have less pressure at the port than a 5.56 dissipator, with the same lack of dwell time. Your plan doesn't sound too bad. If you're just messing around it could be more cost effective to find an already existing rifle length barrel and just have it modified locally.
