With crazystone-like playouts, you can just put "noise" over the
possibilites. the more noise, the more random the playout is, which is
weaker. The best move in the tree is then the one that requires the
least amount of noise for the other player to reach 50% win chance if
behind, or the one that requires the most amount of noise for me if
ahead. Would that work?

This idea makes much more sense to me than adjusting komi does.
At least it's an attempt at opponent modeling, which is the actual
problem that should be addressed. Whether it will actually work
is something that could be tested.
Another similar idea is not to pass but to play some percentage of
random moves - which probably would work in programs with strong
playout strategies. Of course this would be meaningless for bots
that have weak (and already random) playout strategies.

I don't think the komi should be adjusted.
Instead:
Wouldn't random passing by black during the playouts model black
making
mistakes much more accurately? The number of random passes should be
adjusted such that the playouts are close to 50/50. Adjusting the komi
would make black play greedily, while random passing during playouts
would make black play safe (rich men don't pick fights).
