Would it be possible to design a promotion/modifier that adds a new class to a unit?

[Levgre]

For example...

When the unit is given this "promotion", or tag, you may call it, it becomes an additional, 2nd class of unit. Like Melee + Archer.

Or could you just make it become one new class? Like switch from Melee class to something defined as Melee+Archer class?

Seem possible?

It would need considerable re-writing in the SDK to have it grant multiple Unitclasses, since a lot of places in there check for your unitclass and you have to make them account for more than 1 answer (change to a loop). Setting it up so a promotion can change your unitclass will also require SDK work, but not nearly as extensively. Just defining the new class to match Melee+Archer would be the more difficult thing about that. Getting the promotions available for each branch is easily done, but getting Shock/Cover to both affect it would possibly be tricky (cannot remember if that allows you to list a bonus against multiple unitcombats, if it does, then that is easy as well). Those 2 are the only cases where I can think of that the unitcombat is used.
