Im left foot forward and i use to sidehop to my left, but after seeing my mate do massive sidehops and after him persuading me to go to the right i thought i would learn. So for about a week or so it felt dam right awful then it started to feel ok and after about 1-2 months later i could sidehop alot higher and it felt alot more natural. I say go for it, because you will be pleased once you have learnt.
