Upgrading Hubs and Wheels

To make my bikes (more) rideable I have been replacing the original CCM hubs in my 30's and 40's bikes with drum front brakes and multi gear coaster brake hubs. 

Ive found that the Shimano nexus 8 and 3 speeds work quite well for the rear. They are a bit wider than the 37 hub but go in with just a bit of force. Serious frame stretch is not required. 

Also, I have found some vintage sachs vt3000 drum brakes for the front. The sachs hubs arent powerful enough to lock up the front wheel and the old forks seem to take the punishment quite well. 

Has anyone else been doing these sort of modifications? Which hubs did you use?
