It does if you know what you are doing. Juliane Neuss does commercially offer to retrofit an Nexus 8 into a Brompton for almost 20 years now and has done hundreds of those conversions. The hub gets downspacered to a bit smaller OLD than factory and the rearframe get's spread. She and others have also sucessfully manged to bring an Alfine 11 (which cannot be spacered as small as the Nexus) into the factory rear frame.
