Seriously though, I've been tempted myself. I'm sure there is a slight variant between cutoffs for, say, the various manufacturers of JIS tapers for one; secondly, once seated and tightened down, does a significant enough difference in seating (whether mismatched JIS to JIS, ISO to ISO, or JIS/ISO or ISO/JIS) to cause a problem?
Then there's the amount of torque and whether the spindle is greased or not before installation...
