The oilways a complication. Otherwise if always break across crankpin, tension ties could be fitted; fatigue resistance is hugely increased under compression, as big end bolts which would not last long finger tight. 1/2 " ht in a 9/16 hole? Anyone got a stack of thin cranks to play with?
If the cranks would go quietly and not wreck, more inclined to take risks. A noted Seven engine rebuilder here, now deceased, reckoned he never tested cranks.....
Most service manuals regard .030 gap OK for reuse. .006 variation means possibly .003 or .004 wear, by no means worn out.
