Try it and see.  Supposedly you have no data there you want to keep.
There is a current bug that prevents installing (Open)Solaris to a
logical partition but unsure if you can zfs such a partition.

Current practice is not to physically separate data from system, just
use one big "tank".  That way you minimise file system maintenance.
But you can if you wish create zfs filesystems with constrained sizes.

Experts may differ, but I believe the only reason to have system
partition now is because zfs cannot mirror root.  So in an HA
situation you might use mirrored ufs for root and most everything else
goes into zfs.
