A possible use for cleanse?

I know other people have probably thought of this before, but perhaps cleanse on Tahm Kench would be viable? I haven't tested this out personally, but perhaps it would cleanse the slow effect of him eating an enemy champion? Paired with ghost, it could result in an easy first blood almost every time. That is, if cleanse fixes his slow. It could be used to spit the enemy champion into your turret (With ghost speed buff) and have your adc exhaust the enemy under turret. Viola. Fb. Maybe.
