Naw; they make a 170mm KT that looks like you could respace down, but probably not 35mm. Your best bet might be to get a 185mm 3/8x24tpi solid axle, and swap that in place of the factory axle, and add a buttload of spacers (about 15mm's worth on each side) then you'd have to modify (bend) the brake arm so it lines up with the chainstay. Depending on your frame's chainstay and dropout set-ups, it might not work... but it's possible and only having to bend it in a "z" shape to make up for 15mm ain't bad.
