So I see the original Exiles and 2nd Exiles team with Juggernaut, Reaper, Siena Blaze etc were removed from the roster, no mention of them on the page. So should there be a separate team created for those Exiles? Would Marvel even be able to use the name Exiles without buying Malibu? I understand they have next to nothing in common with the current incarnations.

I vote for a separate page, just because they have nothing to do with eachother.

There also was at least two marvel teams called Exiles before the Malibu one.

I agree. They're separate teams. But with the "new" X-Force, it's still the same principle even though it's a different team. So they would stay the same.

Which leads me to my next question, should there be 2 different Malibu Exiles team pages since the 2nd team with Juggs & friends had nothing to do with the original?

I only read a couple of the Juggernaut Exiles team. I'll let it be your call.
