Your process would be Rodinal, expose to light, develop in c41 developer to completion (hold it at 100 degrees for 6 minutes or so), bleach, fix, final rinse. You'll have to fiddle with times and temps and figure out your dilution for the right activity. It's normally 6-7 minutes at 100 degrees for the first developer. Try different dilutions until your slides look good. I think rodinal activates a little bit of the dyes so you might want to try something else to get good whites.
