No, the ReplayMod works by replaying the stuff which has happened during the recording and it is technically not feasible to remove that. There are some small things we could implement to make it take less time but most of them come with lots of very much non-obvious problems attached. And that all assumes an otherwise un-modded game. Once you add 150 other mods to it, all bets are off.
