Drool:
Based on the syllabus the USMC uses for its flight training track, getting some multi engine time/certs would be a good thing to add to your kit bad along with your helo rating. The USMC found that as their initial syllabus from zero to V-22 pilot evolved, that they emphasized the Multi Engine a bit more than in the initial cut.
Been a few years for me, so that's a rough suggestion.
