I don't like the idea. I think it kind of undermine's Archer future role in the Federation that he is manipulating events that eventually lead to him playing a key role in in the Federation. That sounds like a conflict of interest to me.
It also sounds like a TaTV kind of scenario where future Archer, instead of focusing completely on important matters concerning the future Fed, is screwing around with past events sort of like Tweedle Dum and Tweedle Dee (Riker and Troi) in TaTV.
Typical high concept crap that Brannon so loves.
