For me personally, changing to any other kind of FTL system makes it "Not Traveller." It could still be a fun game using much of the Traveller system, but it's not Traveller.
I get what you mean, but I've always seen Traveller as the D&D of space games. Sure, they have the OTU, but the system isn't tied to it like a purpose-built Star Trek or Star Wars system.
If we fiddle with FTL, it would be more like going with spell points vs. standard spell slots in D&D -- yeah, it's not going to look like the OTU to everyone, but it's still "Traveller" in every other meaningful way.

On the larger question, did I detect a desire to go with MT? Or, are we still at the contemplative stage of choosing an edition?
