Actually, you can!  That's what the "ours" merge stratgy is for!
It creates a merge whose result is a verbatim copy of the first parent.

The intended use is for when you've cherry-picked or otherwise manually
merged everything interesting from a branch and want to tie up the loose
end so you can delete the branch name.
