Well, it certainly is not a false statement to say that the B200 simulator could be used for asymmetric practice by a Conquest pilot. Or a pilot of any light twin (except MU2) for that matter.
Because Part 61 dropped the 'endorsement' system for twin engine aircraft and now bundles most light twins together under MEA there would be no reason not to write something in an Operations Manual to say that this is how it will be done.
The initial differences/familiarisation required under Part 61 for these complex types could pose a problem if no asymmetric at all was conducted, but if I was the Operator I would certainly be pushing the case to do no more than a shut-down and relight at safe altitude to cover off procedures unique to the type. Use a simulator for the low level asymmetric. Handling is much the same across light turboprops. The IPC is just an IPC in any MEA, so why not take advantage of the simulator for this to make it worth the travel and cost, further reducing risky activity in the air? Seek relief on insurance premiums.
CASA would need to find strong legal grounds to force an Operator to do otherwise; any MEA theoretically being as good as any other MEA. But in turn the Operator would need to write suitable words into the Check & Training Manual to cover their backsides in the event that some smart-arse FOI decided to challenge.
