Having canti studs means the front braking problem is also solved in a 700C-based conversion frame, but rear may have to be long drop calipers or some other solution. I've almost got my Stag finished, so unlikely to do this but someone may want to do this alone or as a bit of a group buy.
The Rawland version of this was a couple of weeks ago delayed but still planned. A couple of months ago Soma was still also planning their 700C low trail fork for about this time of year - that is one I'd still like to try out.
