Ок, did some riding around, including very bad roads (forest trails), crankdrive works superbly, great help with acceleration from a stop, with one downside - due to chain angle it extends suspension considerably when activated (also there is some pedal bob).
Now that I think about it, there is some pedal kickback as well. I need to lower the suspension pivot or add an other power idler - something I do not want to. There is an other way of changing chain/pivot relationship - lift jackshaft higher, and/or play with jackshaft cog sizes... I see what I can do about it.
