What if the merger were able to modify the tip amount?
A project could have a standard of, say, 0.5% for typo fixes, 1% for documentation, 2% for refactoring which improves Code Climate or coverage statistics...

One plausible possibility that might help: in the block that normally contains Signed-off-by and Reviewed-by, add a tag for marking a commit as "minor" or "trivial", in the sense used by the Linux kernel's trivial@ patches or the GNU project's threshold for changes accepted without copyright assignment.
And as a quick hack, scale the tip by log(diffstat) with a sensible upper bound.
