The only thing that I can think of that you'd need to convert is HPs. Just use the BRP general HP formula instead of RQ2's area HPs. And if your already using the BRP optional Area Hit Points rule you don't even have to do that.
Damage and armor may differ slightly, I'm not too familiar with RQ2 yet. Differences won't amount to much though, RQ2 is still in the RQ/BRP family.
