^LOL!


Yes, with the freehub body swap, you can mix and match cogs to your desire (6/7, UG, HG)

Here's a quick check if it can be swapped.....
Remove the axles of both hubs by removing NDS nuts and cones.
Pry off the freehub body dust caps (6 speed should be plastic, 7 speed should be the standard stamped steel PITA recessed cap.)
Visually verify both bodies are secured with the same 10mm hollow retainer bolt.
If so, you should be good to go for a swap.
