I had to do some info-gathering on genlocking multiple pipes with
differing video formats just recently, so here's my advice...

yes.

Cabling connections should be:
    C/H_SYNC_OUT (PIPE 0, CHAN 0) -> GEN_IN (PIPE 1)
    GEN_OUT (PIPE 1) -> GEN_IN (PIPE 2)
    GEN_OUT (PIPE 2) -> 75ohm terminator

You must use 75ohm video cable.

Need to tell pipes 1 & 2 what the input sync format is...

    PIPE 0: Edit Globals -> SYNC_SOURCE=Internal
    PIPES 1/2: Edit Globals -> SYNC_SOURCE=External
               Edit Globals -> SYNC_FORMAT=1024x768_120s.vfo

Kind regards,
Tom
