Idea for a new civ capability, villagers who can ride on the back of (garrison in) a scout

It would be interesting if there was a civ with this capability. You could maneuver them around the map quickly, or move villagers with a little extra protection since you have to kill the scout horse to get to them. But you have to pay for both a scout and villager to do it, and the villager can’t work until it gets off.

I wonder if it would work and how it would play out. If it would even be useful at all.
