I believe a sight off a MKII bull barrel should fit. The barrel radius will not match perfectly, but... that's why you're experimenting!
I've seen guys do the reverse of what you're doing- they've taken a Single-Six front sight, and put them on the MKII.
The reason stated was to get rid of the "holster ripper" undercut front sight on the MKII.
I've got a picture, somewhere...
