@Riot Thoughts on making a channel in the river?

The river would remain in it's current state aside from a deeper channel in the center that would slow your move speed for a small amount unless you picked up the scuttle crab buff. To a point that would still give risk-reward aspects to invades and roaming in general. Thoughts on how that would work with all the champions blinks, dashes, teleports and the such.. ?
