As3.0/HTML 5 conundrum

I want to redo my portfolio and make something super interactive, with some characters kicking around and some other animations. My problem is having spent a couple of days working on a HTML5 and JS version I cant really get anything Im happy with. I am tempted to have a full flash version, then a mobile/none flash version of the site and maybe a small app built in AIR. This seems a little laborious but I cant think of another way. Either make 1 full flash site with a scaled back version or battle on with a HTML 5 version?
