I don't emulate at the moment, and can only play games I actually own (for now). I only have a few Megadrive imports, a handful of various handheld imports, a decent amount of Saturn imports, and a LOT of PC Engine imports (way more than TG-16 games, weirdly enough). With that said, I don't mind the inclusion of an import or two here and there. since there's always going to be something I don't have that others have access to anyway in the weekly picks.
You may want to consider keeping some of the import picks broad though if you decide to incorporate them. Like instead of always using individual titles, you could sometimes just have a broader criteria, like 'an import vertical shooter', or 'any import game based on an Anime license that wasn't released outside of Japan', or 'an import installment that we didn't get here for a series that we did get, etc..
