I'll tell you right now, you're never going to see Megaman X4 on PSN. It's English voice cast are not co-operating with Capcom.
Now, I'm sure it's possible to be released. Probable? No. That game came out in 1997, it would have been out on PSN by now. Releasing Rockman X4 as a Japanese import may be an option, but, that title might carry the same issue.
If you have a problem with owning disc versions of those games, then, that's your loss.
