Something my sister-in-law used to do on CoH was use the run fly glitch, where you could run in the air, to be able to do a makeshift hoverdisk travel power. If a glitch can do that, I wonder if it's possible to just make a hoverdisk travel power, basically a flight power using the powerslide animations. Working with demos I also know the superspeed sfx works really well as a hoverdisk as seen on this video:
Also, just a run on air travel power would be pretty cool to, ala Gwen Tennyson's stepping stones power, or like in Doctor Strange:
