Also, do you think if I got MV-22, I would be good to go for the airlines?

I'd definitely will want to avoid drone flying at all costs. First off, I don't even think regional drone flying is ethical.
Out of curiosity, what do you define as "regional drone flying?" You may be in for some ethical dilemmas if you join any of the services, as you'll no doubt be sharing airspace with something that's umanned providing support.
