a installed legit cia will stay installed if you revert to OFW and will work.
the only way to get a legit cia installed on OFW currently is by a system transfer (which will copy the legit cia over), or buy it. Pretty sure you can install legit cias onto a cfw system, then system transfer them to an OFW. This way you can get a OFW 3ds with all legit CIAs.
