Cross Country (Classic) Grooming Width & Back Country Skis

I am curious, has anyone heard of cross country ski groomers using different widths for the classic track grooves, so that that they can be used by backcountry skis? I am a 400+ lb person, with some leg injuries, and I find that backcountry skis are better suited for big people, because they are built heavier duty and they are better designed for turning. That helps out when you have less mobility, and less flexibility. Thus they help enable someone like me to get out and exercise in winter.

I got a pair of backcountry skis a couple years ago, and when I went to the nearby city there were ski trails that were well used there. They had a sprint track next to a parking lot where the classic tracks would get worn out oversized (larger then originally set) due to the high traffic, and they worked well for backcountry skis. That winter I lost roughly 30 pounds just doing a short mile (or so) a day loop on cross country skis. This year I am now in a small town, where their tracks are the classic width, and they are don't get worn out like the cities. I doubt and question them welcoming people using backcountry skis on classic tracks.

I was wondering if there was any precedents of other ski areas adopting wider backcountry skis track-groove widths, so they could be more inclusive for backcountry skis, telemark skis, and off trail touring cruising skis (and maybe randoneering (sp?) skis). If there was precedents in other places around the world, I might consider trying to convince my local ski area to change over. If they did it, they would be more inclusive not only to people with other types of skis, but also people bigger people, and those with injuries. Does anyone have any thoughts on this?
