I think that you're missing the point, Hydor. What we saw in "Bloodlines" makes it clear that if Impulse continues on his current path with his current plans and methods of changing the time-stream, somewhere along the way, things are gonna get out of his control and he is gonna fail. The only person who would be able to warn him of that upcoming failure and put him on another path to using the correct methods of "crashing the mode" would be another time-traveler. And if he isn't shown the error of his methods until it's too late, then at that time, the only person who would be able to show him where he went wrong and take him to a time where he can start over and use the correct methods would, again, be another time-traveler. No matter who he enlists from the present to help him or what he uses, at the direction that he's going now, only the appearance of another time-traveler can bring him on the right path and help him in changing the future into a better place.
