I was thinking about it a while back as that is something the Limited had that my EB didn't. I've been sidetracked with other projects, but would still consider it if the time and price was right. I'm guessing it wouldn't be cheap though.
The two things the Limited has that my EB doesn't are the power folding mirrors and rear heated seats. I have since dropped the idea of getting power folding mirrors as the factory mirrors absolutely suck for trailering anything of significance. If I do any sort of mirror modification, it'll be getting something fabbed up to allow telescoping mirrors to fit our doors.
