Actually a quick glance at git-merge, a rather large case...esac after
that "show-branch --merge-base" tells me that we do not really use the
output from that operation and instead we check if we are fast-forward
from all the other heads by iterating over them. merge-octupos would
accept it as the base but never looks at it.
So I think with a proper refactoring of the codepath you probably would
not even have to do the blanket "merge-base across all heads" at all.
