If the producers still want to use the old cast, they better separate or kill-off some of them
Hehe.
But seriously, I'd love to see Kagalli as the ONLY regular recurring character from among the old main protagonists. Eventually, there'd be some Dearka and Yzak. To me they're like R2D2 and C3PO in Star Wars - they gotta flash in every series here or there :P The rest could be entirely new.
