Inviting too many social awkward people into group. Now I don't want to be in our group.?

OK I have a group of around 6ish people. We're fine like that. Don't try and go for people who don't have friends or have a group. To be honest, they are the ones that aren't 'out there' at all. I have a group in my year and they didn't have any friends until recently. So the group of people with no friends made a group and now they are friends haha (that sounds weird).
