That would require some redesign;  note that the current process is:

  - update-grub sources /etc/default/grub
  - update-grub exports a number of predefined variables
  - update-grub execs every script in /etc/grub.d/

So right now variables set in /etc/grub.d/00_foo can't be used by
/etc/grub.d/10_bar.

What does this do?  It doesn't seem to have effect when GRUB_CMDLINE_LINUX
is already set.

How would this work?
