Allowing allies with teleport summoner spell to swap places.

I have this idea about allowing 2 player equipping teleport summoner spells to swap places.

Player A and Player B both have Teleport summoner spell

Both Teleport spells are ready for use.

Player A use Teleport on Player B's champion.

Player A's champion starts channeling.

Player B's champion will have visual effect while pending for action

Case1) Player B hit Teleport within the Player A's channeling time, Player A's channeling completed, both champion swap places. Both summoner spell on cool down.

Case2) Player B ignores or does not response within Player A's channel time, Player A completed channeling but nothing happens. Player A's CD is considered as the spell has canceled, but Player B spell is ready for use.

I think this will be fun and provide an alternate response for opponent's lane swap.
