You're reasoning works for me.

The value of a specialist unit depends on the situation, so I think "balancing" them with a high cost for previously published scenarios makes sense.

Generally I like to see the type and amount of specialty units specified in the scenario set up. They are supposed to be scarce after all, not widely available like the standard units.

I do like the option to take a few to support a particular strategy, and making them expensive means you need to have confidence that they'll pay off.
