It's a good look, if you can find a wheel setup that has the same design in 19s and 20s. It's actually harder than it sounds to find that.
If you do it, you should NEVER EVER EVER put a shorter sidewall on a rear tire than a front tire.

Don't get too crazy with the wheel diameter mismatch. Here's 18s and 20s.
