Well it won't directly enhance your running - but if you're doing it on a rest day and it doesn't interfere with your running - then why not.
Define 'enhance'...........
Your version of enhance might be a 30% improvement in your marathon time ...... my definition of enhance might be a 5% improvement in your marathon time.
Then you might say 'well isnt any improvement better than none.'
But heres the thing ...... on my days off, Id actually rather have the 'day off' ..... not also do little bits and pieces here and there, so my body never actually has a full 24/48 hours to recover ...... days off are just as important and I think sometimes if you try and fill it by doing itty-bitty things you are probably doing more harm than good.
Not saying, don't do hoola hooping, but just saying is it probably the most efficient use of your time? Probably not, but if you enjoy it, and realise that its probably not the most efficient exercise you could do, then by all means, go for it.
