Koxx ISISTrials Cranks Alternative?

I am starting to do more trials and i dont like the feel the k1 trials cranks have to them (but i have only tried them in 125mm, are they any better longer?). I have heard of people putting moments on their k1 hubs, so basically what im wondering is if i do this what are the possible outcomes, and i don’t mean worst case situations, cause i know those.

EDIT: I currently have k1 street cranks.
