Yes you can. I replaced all three of my MaxxFan lids with smoke color (since my RL is black/silver). Problem is, you have to order lids from factory.
Open lid, remove phillips head screws on both ends. Use ice pick or scratch awl to push long hinge pin out enough to grab & pull out with pliars. Reverse to install. 5 minute job.
