I have never ever heard of anyone doing that, but given enough time and a good welder anything is possible If you manage to pull that off, post a tutorial, and get rich selling conversion kits.. Don't forget that the W110/111/108-axles have the gear casing slightly offset from centre, and the later models does not, so that might give you some issues with driveshaft clearance.
Btw, is there any particular reason you'd want to do that? The swing axle performs quite well for it's age and if you want the disc brakes a 108-axle will do fine.
I'd think a 108-3.96, 14 inch wheels and a fifth gear would be the most cost-efficient and easy solution for you.
