Some of your list is correct, but some isn't
You will need to modify the following if you want it to work correctly with a WE:
Selector switch ( I believe you have to modify the selector plate for it to work properly , Upper reciever (the trigger box needs to be cut down to allow for a RS upper to fit, the charging handle, and a real bolt catch wont work as the WE bolt catch is different from a RS bolt catch. You can use a RS buffer spring, but I don't know if your bolt will lock back, you probably wont get a full mag off and your cool down with be the worst.
