Look forward to your news and good luck. I'd love to be able to do roller dance well - I try some stuff on inlines but I lack the flow. I love skating on wheels for the fresh air and freedom but there is something unique about newly resurfaced ice - an ease of movement, easy, smooth speed, and the blades are so responsive to tiny movements of your body.
There's no reason you can't do both. It took me a few months to be able to switch at will and not have it feel strange. It's also fun adapting figure skating moves to wheels and vice-versa.
I expect the toepicks and edges might catch you out a bit but all the stuff about posture, knee and ankle bend should stand you in good stead.
