Ideally you need a drop-specific frame, which will have a shorter top tube. If you fancy trying out it on your Inbred anyway you want a very high-rise stem, and even then it may feel to stretched out and too low. Be prepared for an ugly set up!
I love riding on drops, just for something different, but I have a flat-bar’ed bike as well. I don’t’ think I would have drops on my only bike tbh.
