You can just use extra FICON interfaces as FCTC's. IBM refers to that method as a baby sysplex. It allows you to have GRS in ring mode. TO have star mode you need CF's.
If you have multiple LPARs and you share dasd, then you need either CF's (expensive) or Ficon CTCs (pretty cheap). The setup is very simple. CF's are much faster but ficon CTC's easily handle 3,4 or 5 lpars without any issues at all.
