The FAA opinion re. Osprey time is an expensive nuisance, ie you might need to buy time in a 172 to meet ATP mins.
The bigger issue is do you have enough FW time to meet airline (vice FAA) minimums?
My guess is that you don't even if airlines count Osprey time, which I'm not sure they do. Some airlines have formulas to grant partial credit for RW time, V-22 may fall under that. I don't think you're even in the ballpark for major airlines, so you'll want to research hiring mins for regionals. Each airline will have a different policy for RW time.
Airlines view Harrier time as FW because harriers can and do land like airplanes. MV-22 may fly like an airplane but it lands like something else entirely.
As someone mentioned, emerald coast could probably give good advice.
