I think it's probably doable, but you might have to cut off the barb below the thin OD so you have enough wall thickness to provide the threads some strength.

I was thinking of going 3/8" NPT which would be even bigger, but I think the real gain is on the outlet side especially if you could straighten out the flow and tap in the barb just right to get that straight exit.
