Considering git-commit doesn't allow this (probably for good reason),
is it technically safe to do the following sequence of events?

tree=$(git-write-tree)  #basically the same tree HEAD points to
commit=$(echo $IDEAS | git-commit-tree $tree -p HEAD)
git-update-ref HEAD $commit HEAD

This can also be written shorter, and safer:

	head=$(git-rev-parse --verify HEAD^0)
	commit=$(echo $IDEAS | git-commit-tree $head^{tree} -p $head)
	git-update-ref HEAD $commit $head

The reason you do it like this is it prevents a HEAD which was
modified between the time you did git-commit-tree and git-update-ref
from being lost.

And the write-tree is completely unnecessary, and might actually
write out a dirty-index, which would make your ideas commit actually
modifying files - not what you wanted.
