Mart,
Wish I could help you on the technical questions, but I’m only familiar with the historical details of the XV programs. I believe the 'tip jet' technology was only used on the XV-1 and not on the XV-2 proposed design, but cannot confirm. I have a friend at NASA who worked on a later XV project, and if he approves I will send you his e-mail address (check your PMs).
