I think that 'telekensis' attack is just Frieza expelling his ki in an invisible form. Powerful fighters do that every now and then in the series - watch Gotenks fighting Fat Buu, and see how his punches leave marks even though his hits aren't connecting. It's just his extra power making some sort of invisible force.
Still, it'd make a nice move. If you aim it right and hit the button, you can slam them across the map - kind of like a hit in melee as it is now. If they hit a wall, they take extra damage, if they recover, they take none.
