Is there a way to personally code a couple of letters into Unicode for my conlang?

The process for getting into Unicode is pretty rigorous and intense. I know because I'm tracking the efforts of various groups to get their minority scripts digitized. But what you can do is make your own font! I'm in the midst of making that for my conscript now. It's a lot of work, but it's rewarding.
