I'm really not following you. Touching down at 60 knots is not an "impact". To stop, you simply use the brakes (maybe a bit more forcefully than usual, because you never know) as with any other (controlled) landing. Even if the gear were to give way, you will not stop abruptly and the kinetic energy will be dissipated gradually. The only case in which the aircraft will always come to an abrupt stop is when the chute is actually deployed! For the comparison to be meaningful you'd have to hit a concrete wall right after touch down, which would mean either that there really is no suitable field available (in which case pull the chute) or that you're not capable of putting the aircraft down where you want it without power, in which case you shouldn't be flying it to begin with.
