Within the one CEC, adding one more is probably no big deal. We ran across two sites (~10km) - and DB2 starts were awful. Especially more than one system coming up together after a PoR. TSO logon procs with large DD lists is also a no-no - see Toms dynamic stuff to help there. Shared catalogs on HCD defined SHARED volumes generated enormous traffic. But you're probably already suffering all that - or not, in which case you won't care.
Maybe run the GRS monitor for a while - before and after. Will at least give you some ammo. I found running a CF LPAR just for GRS STAR was beneficial. Anyone with a real CF will laugh at the numbers you get, but in our case they were significantly better than the ring.
