Let Mordekaiser Ult Vilemaw

I would like to see Mordekaiser be able to ult Vilemaw and carry him around like Dragon. I'm not saying it has to be hella strong, but I mean.... Mordekaiser is from the Shadow Isles. I think because there are only three people to fight it it shouldn't be as strong as Vilemaw, but it is his ult so it shouldn't be a pushover either. It should require some effort to kill. It should have enough power to make them hide behind a turret 4v3, but not enough that it's gonna plow through the lane. Thoughts?
