Just a suggestion, but if you had to get the big end shells made up, couldn't they include side "lips" like a crank thrust bearing to make the difference in journal width & prevent float.

I'd be tempted to agree a better solution would be 5.85" blanks machined to take stock shells & pins, guess it depends on feasibility of any solution to the narrow big end.

(actually, some motorcycles use the small end to locate the rods laterally particularly on roller bearing bottom ends. Would the extra width up there help you work a solution maybe with two piece top-hat bushings? )
