Five channels of genlocked frame syncs could easly cost you more
than buying one of the "industrial" asynchronous switchers (which
commonly have four inputs, but you could externaly switch between
your DVD decks, etc.)

You need one frame-sync per input. One would assume that "dual
channel" frame syncs have two independent units. But I wouldn't
bet my budget on it without confirming it first.

A frame-sync *without* a genlock function is useless to this application.
It is no better than what you have right now.

Yes. If you had three "dual frame-sync" devices which really have
independent genlock adjustments and separate video processing,
that would do it.
