The tilt rotor guys wing with us so they most likely could come back to VT-35 (TC-12s).
Unless a few instructions get rewritten, I don't think tilt guys can come back as HT IPs (need a HAC designation for that,* and for HAC you need to meet r/w hour requirements). So it looks like VT or VT-P for now.
*I can't remember the reference off the top of my head
