Seen the opposite being done is crinkle hub into B50, just a matter of spacers. The conical is heavier and you lose the QD.

Go with the crinkle hub.
The conical hubs have problems with bearing seats. The bearings come loose and the housing cracks around the bearing. Not enough metal in the casting

I did this on my A50 cafe racer. The earlier swingarm for the Star models was shorter than later ones by a few inches, which shortened the wheelbase. Thus making it quicker to turn. Coupled with the alloy hub, meant for lower unsprung weight, so I thought, mmm. From memory, you need to start off with a spindle for an OIF wheel, and it's spacers. You then need to make or use additional spacers to line it up accordingly.
