I went the same route as you with the wrinkle cover but I got mine engraved with a drawing my friend did. Had to replace the stock chrome one because it got a boo boo, you can still see it in my primary cover...
How hard is it to change the derby cover? Is it something that can be DIY, or should it be left to the pros?
It's super easy....make sure it's on a stand, or your buddy is sitting on it and keeping it vertical. I'm impatient so I just propped my kickstand up on a 2x4 and pretty much had the bike close to vertical, no spills. But I don't recommend that 2x4 method...I have no sense If it's a stock type Derby cover it should use the same Torx screws and rubber gasket that's on the bike. If it's custom it'll probably come with different screws and a different seal.

You'll need:
-A set of torx bits
-1/4" torque wrench
-A way of keeping the bike upright (I recommend a wheel chock/stand)
-New derby cover of your choice
-A new flat gasket to replace the stock o-ring one (HD part #25416-99C)
-About 15 minutes of your time
