Your suggestion makes sense in principle. However, it is
/usr/share/initramfs-tools/init that performs the mount, so that's what
would need changing.

As a workaround for your situation, I suggest adding a kernel parameter
initramfs.runsize=20M.

Would you be able to provide a patch here? I think that if a runsize is
given, it should be honoured, so it would probably work like:

if test -z "$RUNSIZE"; then
	if system_has_at_least_200mb_ram; then
		RUNSIZE=10%
	else
		RUNSIZE=20M
	fi
fi
