There are already mag motors in DSL... some of the best motors available too, in my opinion.
Also it should be noted that we're not going to be adding anything more to DSL 2.0 now unless it is: 1)Necessary 2)Quickly and easily made and/or 3)Unbelievably, revolutionarily awesome. Since I'm preparing the mostly complete beta version for download right now (please don't ask to be beta testers, any of those we need will be asked by the DSL team).
