I think the hardest thing will be to find a sim that is approved by both the FAA and your local CAA and to get the two inspectors together at the same time. Also if there are things one requires and the other doesn't it might be confusing.
You don't need any medical to take the check in the sim, however you have to have a current First Class to take the written. If you have 1000 hours on the plane, you shouldn't have much of a problem on the oral. You should be able to explain all the switches and lights on the panel. And give an overview of all the systems. Plus the memory items on the checklist. You may also have to do a basic performance problem, runway required with snow on the runway or something off the performance charts.
I would think you would want the PIC type rating, the FAA doesn't even do the checkride for the SIC rating.
