Hi klondike.
In EASA OPS operators you have to fly only ONE type of aircraft, you cannot fly simultaneusly 2 different Type. Normally an operator performs 2 checks (minimum) each year, 1 LPC (Licence Prof. Check) and 1 OPC (Operator Prof. Chech) in the SIM session (every 6 months). I don't know the carrier you're in contact but in EASA they request a recent activity in the type (LPC or OPC normally it's the same profile of check).
