Converting a snowmobile trailer to an LQ/Toyhauler

I currently drive a Sprinter Cargo Van all over the country teaching seminars. But with 300,000+ miles on a 2002 Sprinter, it's time for a new road vehicle. I'm toying with the idea of converting a 7' by 18' to 22' snowmobile V-nose trailer into a front office/LQ with the back 12 ft or so reserved for the 3,000+ lbs of seminar gear. I would probably tow it with a 3/4 ton diesel pickup of some sort.
Of course, most snowmobile trailers have a ramp door on the V-nose, which would serve no purpose if I just put a partition wall between the back cargo and forward LQ areas. However, I've had this brainstorm about using the V-Nose ramp as an extension to the living area. The idea would be to block the ramp so it only goes down to level, and have some sort of folding-wall or canvas topper that would cover this ramp-room. Hey, I could even put the bed on the inside of the ramp so it would ride vertically on the road, but then be positioned properly anytime the ramp door was in horizontal position.
Something like this for a donor trailer. Of course I would add some sort of "stop" so the front ramp only goes down to horizontal, not the ground.

I've asked around with my RV conversion buddies, but nobody has ever seen anything like this. So, does such a conversion exist that I can see for ideas? Are there any tent fabrication companies who could make a canvas "tent" that would automatically open up over the ramp-room as it was lowered to horizontal position? Any other places to look for ideas on this type of conversion?
Thanks for any input you can provide.
