So, each civ has a Unique Unit. Many/most/all of these are replacements for regular units. Theoretically, all UUs are better than the regular units they replaced.
So, as an example, there are several UUs that are replacements for the Knight, which is the upgrade of the Chariot. Given that they have the origin from Chariot in common, might it not be feasible to take a Knight given to you by a Militaristic City State and convert it to your civ's UU (assuming that your UU is a replacement for the Knight)? If it were possible, the cost wouldn't be as much as Upgrading from Chariot to Knight/UU; maybe half that cost.
It seems to me that it should be doable, given that the bulk of their training is similar. And of course, the conversion would be limited to YOUR UU only.
