Uhh... getting difficult to understand you there but the concept would be okay if you didn't use Rayman as a playby at all but a different picture, yes. Provided some small things get changed:

Having your body parts being perpetually suspended by magnetism seems impractical and might not even be possible to do for any long duration of time on a count of the constant focus drain necessary to actually control the magnetism so your body parts don't just fall on the ground or just stick to anything metal. It'd also be a huge risk whenever they come up against anything that could manipulate or disrupt that magnetism.

How about instead of being constantly separated, you only separate the parts when you need to? Like for instance, say your character needs to grab something from a distance, you could temporarily detach their hands to grab it from afar and then pull it back. You're still using "magnetism" but it doesn't have the same downsides like above.
