I would think the old 750MC idea of a second pair of oil jets at the bottom of the crankcase pointing upwards is the ideal solution.
One set of jets would be directed to one pair of pockets and the other jets aimed at the other pair of pockets.
Details are either in the 750 Companion or the Special Builders Guide.
I have an 1 1/2" splash fed crank which I believe is an Allen Crank with Nippy Rods. When I find it again I will measure the pocket centres.
