Using current animations as Recalls for older champions

As the title suggest I think it would be worth considering to use current animations as recall animations on old champions.

Take Tryndamere he has an animation where he stabs his sword into the ground and does push ups then stretches a bit. So what they take out the push ups and stick on his spin animation at the end. So he stabs his sword into the ground flexes his muscles and then spins into the air.

Then Xerath has one where he forms into a sarcophagus. So he could form into that form and float into the ground or something.

Volibear could taunt and then use his channel animations to make a cool recall.

Those are just my ideas.

I just think there are a lot of cool things they could do with a lot less effort by using old animations in recalls for champions. Something similar to the texture rebalances.
