Hell, I say go ALL IN with the time travel. Maybe one of Jonathan Archer's descendants is a time traveler from the 29th century (who also happens to LOOK like Jonathan Archer, since all descendants obviously look like their ancestors

). He's sent back to prevent a Suliban from sabotaging Captain Archer's maiden voyage of Enterprise. Something happens, Archer's descendant fails miserably, and Captain Archer dies. So, unable to return to the future because it doesn't exist, Archer's descendant has to take Captain Archer's place and try to recreate Jonathan Archer's voyage. From memory. Without blowing his cover and fighting off temporal agents from the future (don't ask me how there are still temporal agents if the future doesn't exist, something about hating temporal mechanics, or whatnot

)
