Trade 38mm KH 29" wheelset for 47 mm KH 29 wheelset" + $$

I only ride my 29er offroad and I dream of the wider freeride rim. Does anyone in the US want to trade a freeride wheelset for a narrower wheelset? My narrower 38mm wheelset is in prefect shape I’d be willing to kick in a little cash to make this trade worth your while. THANKS
