Personally, I wouldn't. I've dated other trans folks in the past, and their dysphoria plus mine was awful. The only way I could see it working is if we were both in maintenance mode, post-transition. And that's often pretty hard to come by, at least in my experience.
I would especially worry about dating someone that won't transition - "won't" being the key word. I know that transition is personal and it looks different for everyone. The medical community has agreed that transition is the cure for gender dysphoria. My worry would be that the person isn't addressing their dysphoria or trying to do anything about it. That would create extra baggage, and it isn't something I'd want to expose myself to.
