I like it, certainly gives the Monty a different look. Didn't think about what's actually supporting a roof rack though, until some folks mentioned it in here. I just got a Yakima roof rack that clips to the gutter rails, with 48" cross bars, for $75 off Craig's List. Got it mounted tonight, and it looks pretty good, and it's on there good and tight. About the only thing I plan on carrying up there is a surfboard or two for my daughters, so it was well worth the $75. I also have one of those hitch mounted cargo carriers, and plan on bolting a plastic storage box to it so they can put wetsuits and other wet/sandy beach stuff inside of it, and will drill some drainage holes.

But I like your plan for that Xterra rack...
