I don't see why not - just like a transformer, if it was not reversible it wouldn't work for receiving signals properly. After all when you receive through it the antenna impedance is scaled back from 200 Ohm to 50 Ohm, is it not? If this is the case it'd scale 50 Ohm down to 12.5 Ohm just fine.
But... If your antenna has 12.5 Ohm of resistance, what is its reactance? If it is way too high it will not work efficiently no matter what balun you use. And out of those 12.5 Ohm, what part of it is radiation resistance?
