You could always paint them, or polish them. You could wear out the tires that are on the comstars before you go back to spokes too.
Does it ride any differently with that 17 on the rear? Lowering the rear a little like that should increase the trail making the bike a bit more stable at certain speeds, but handling may be decreased a tiny bit at slow speeds.
If you like them keep them, it's your bike and it's cool. I'm not a comstar guy though, I'm an alloy wheel guy.
