Unfortunately, it's not possible to do it with
playback rate change.
You will have to either do it over or do a post
process. Sims are dependant on the framerate. If
there were a way to do sub-frame sampling it could be
possible.
Personally I think it's a really bad idea to tie the
sim to the playback rate, these are the kinds of
problems you have as a result.
