I'm curious as to whether anyone has tried it (Steve Parry or the likes)?

While I love my Tikit with the Capreo, I can't help but long for a smaller fold (to be less obtrusive on the bus). I already respaced the rear axle and it looks like I could knock another 8mm or so off of it, so I'm considering trying to get ahold of a Brommie and having new drops welded on
