Based on the picture, if crankcase, camshaft or whatever would permit it, I would want to adopt a greater taper in the beam, particularly being wider at the juncture of the big-end reducing the 'shoulders' or distance from the beam juncture to the bolt-posts; otherwise just additional heft to these 'shoulders' to reduce the tendency for the big-end I.D. to change dimension upon being loaded.
As for a rather exaggerated example, look at the Ford/Mercury M.E.L. 430/462 connecting rod. Though to much and one finds that in machining for the retaining bolt, one creates effectively a 'notch' this in particularly the "I"-beam flange,........not good!
As I often say: Just another comment from the peanut gallery!
