yes, you can copy OEM's from another kitchen from the OEM folder, but if you're trying to copy a OEM from a ROM, that is much harder, as the OEM will NOT be in it's own OEM folder, the files will be scattered throughout. technically all the files from that ROM will be in there, but it would be very difficult to copy.
your best bet is to ask others to share their OEM, or search the FTP for the OEM your looking for or create your own.
Here is the OEM creator you asked about....
