Allow players to attach themselves to a locked squad as an affiliate, solely for spawning purposes. These affilate players could have the following characteristics:

• Purple name tag
• Does not have access to squad radio communication
• Can spawn on squad members
• Squad members can spawn on affiliate player
• Can place beacons for squad members
• Squad leader of a locked squad can make affiliate player a full member.
• If more players join the locked squad, attached affiliate players are removed to make room, if necessary (maybe only post-death).

The attached picture shows a situation that could be alleviated by this kind of addition. A fractured team consisting of multiple locked two-mans squads give very limited spawning opportunities and drags the whole team down. It's particularly bad for the 1 or 2 leftover players who don't get a full squad, especially if they're Recon players whos primary utility is the spawn beacon.
