If you mean classic code (old ROF2 MQ2, vs. newer ROF2A MQ2, or ROF2 MQ ala next), you can if you have a copy of it. Just drop in the loader from ROF2A, don't let it patch your plugins, and ignore any out of date warnings it mentions.
Neither of the non-next versions work for me with any combination of mmoloader binaries. Just acts like it's starting then exits. Same thing it's been doing for a couple weeks
