As noted - it depends and there are variables that specific each engine and/or drive system(s). It ranges to swapping out wheelsets to significant machinist effort.
There is a good level of experience in residence here. Suggest that you consider posting a short list of those specific engines that you would really want to convert to see which have or not been converted by folks here to gauge feasibility.
