Yes, absolutely I have thought about it. Originally, I wanted to chrome the rails because they are the only brushed aluminum trim on the whole car. Thought I might as well match the door handles, body trim, grill, wheels, etc. Never really made any decision on it tho. Like you said - I have other things going on that take priority. Looking at the red FXs that have the rails painted, I don't like them as much. I feel like the black/red theme is less classy - less luxury - less Infiniti, than the OEM color package.
But my "vision" for the completed FX includes painting all the gray body trim to body color, as well as inside the headlight housings. I was going to include the front wind deflector as well - one member here has his wind deflector painted to body color and I think it's a big improvement over the stock wind deflector look. The FXs that have painted the trim look more classy to me, more like a Mercedes than a Jeep - which is what the OEM grey body cladding reminds me of (I had a grand cherokee with grey side cladding).
I've toyed with the idea of removing the rails completely as well, but on the FXs I have seen that have them removed I sometimes don't like the look from certain angles. I haven't been sold on any one solution to the, "roof rail dilemma". Fortunately it's not that big of an issue.
