Don´t mix the RP´s history tells us that there will not come something good out of it - meaning: do not use multiple RP´s.
For ASF/CSF - why not thinking about other scenarios like ASF or CSF Trains protected/attacked by the half of the Server population while transporting weapons to resistance in hostile territory. We had such ideas running in the past - and the scenarios was great - i remember IOC (either Mercs) switching Sides in the middle of the Battle - damn what a surprise ASF/CSF is your Game you can make anything you want out of it, if the parties will do it together - and they will, if it will bring more fun.
