Apologies if there is already a thread covering this topic - in fact, I could have sworn I stumbled across something like this accidentally one day, but I couldn't find anything with search.

I want to know if it's possible, on an open-jaw ticket, to combine awards of a different series. Specifically, I want to fly from AUS to IST, and return from AMM, all in J. I think this would be a Series 6 on the outbound (100k round-trip), and a Series 10 on the return (120k round-trip). I guess if this is possible I would expect a 110k cost for the trip.
