Are these environment variables being *set* from within grub itself,
or by an administrator booted into an OS? For persistent storage of
environment variables you can simply set the variables with the
grub.cfg, or in a separate cfg file which is sourced by the primary
grub.cfg (like /boot/grub/custom.cfg). Using a normal text file you
can include as many variables as you want, expanding as needed.

That's not to say that it will never be useful to have a larger
grubenv, but it doesn't sound like it's needed in your case.
