Hey
@NuevoXS,
Still sorting out the various details of what seems to be working for people in different situations.
From what I'm seeing thus far, you should be able to try just replaying the last mission in ME2 for that to trigger, assuming you had a save game at that point.
That said, for Paramour it seems you don't need to complete the final mission in ME1, just load a save file and save over it.
It should be fairly quick to just load a ME1 file and re-save it even if you're just going for the Insanity II achievement, so that may be worth doing before re-playing an entire mission in ME2.
