As promised, here is a mobile list I came up with that completely lacks any static units. First to go was the Aegis, then the Fireblade. Every unit in this list is either in a transport, jet pack (and thus can deepstrike) or outflank. It you're playing a highly aggressive (demons) or mid-range shooty army (grey knights) it should work out great forcing your opponent to split his forces. The closest thing to static is the Skyray.
There are a couple things I'd like to do, for example give the missile suits skyfire.
I still want to get 1-2 Riptides. I would replace all 3 units of crisis suits with 2 riptides if I had them.

That's is. Highly mobile, very flexible deployment options, and still has decent firepower thanks to the multiple weapon faq for the crisis suits.
