I can make a few suggestions of smaller FC's that may interest you:
<<FUSE>> has about 25-30 members, you can contact Maya Neko for information on their FC
<<Tiro>> has 19 members currently and you can contact Aki Tomoui
I would suggest <ISIS> they have about 35-40 members but I think their recruitment is status is more specific and they might not be open to the idea of mergers, but if you wanted to can contact High Timessw and ask them.
I dont mean to speak for these FC's but they are smaller groups with great people, I don't know their individual progression other than <ISIS> that has downed T5 in BC.

If you was open to the idea of merging with a larger FC then I would recommend <DNite> they are currently looking for smaller mergers and are a absolute delight to work with, if you was interested and want to speak to them contact Lasse Salander.

I don't know if FUSE or Tiro are open to the idea of a merger, but I do know they are good peeps and it wouldn't hurt to message them.
