Yes, I do exactly that, and have done that on all my computers
for years. You can create a small partition to install Grub alone.
Install Grub to MBR and later Grub stages to to this ext3 partition.
All GNU/Linux distros installed on said system have Grub installed
to their own root partitions. (chainload Grub to Grub)
Or if it be a great hassle for you to create a separate Grub partition
as you now have your drive(s) currently partitioned,
just use the first Linux partition that has a GNU/Linux distro installed
on the first drive to install Grub MBR and later stages to,
and chainload the other Operating Systems
installed on drive(s) from there.
