FC vs LS quantities

My LS has 110 people in it. No, they aren't all active or online at a time, we usually have 20-30 people on during peak hours, but we're coming up to the point that the only way to add new members is to kick old ones. On the flipside, an FC can have 500+ people (I think, I can't log into game on this pc to check exact number).

We could just remove inactive members, but we have people returning to the game and being active with us after not having logged in for months, and I don't want to make members feel like they have to log in regularly or be kicked out. One of the members made a good point in that the FC and LS quantities really should have been switched. I'm sure there's reasons for the lower limit on LS members (server strain? Idk) but considering that each player can only be a member of one FC but have multiple LS's, it seems a little silly.

Is it at all possible to get an increase on the amount of members an LS can hold, if only a little? Our's grew mostly from a few friends inviting their friends who invited their friends, and a bit of recruiting on the side. I'm sure there are plenty of other groups out there who struggled with the cap long before we did.
