NACK.
The way rwtab normally works is that it creates a tmpfs and symlinks or
bind mounts it to the locations given by rwtab.
But this means the data will be discarded at the first reboot.
SSSD data is not just cache, sssd.ldb has to survive across reboots so
this approach is wrong. True sssd will start and work, except you will
loose everything on reboot.
I do not want to endorse, make it easy or even recommend to create such
a broken configuration.
/var/lib has to be writable and not shared if you want to run some
services, and if you want it read-only/shared/etc you better not use
sssd.
Simo.
