I'm not sure, if that would help. If I've understood correctly, the number of servers (and the distribution of balances between the servers) is more relevant than the number of forging accounts. If you have multiple accounts forging on the same server, wouldn't they all end up in the same fork*? At least the opposite is true: I have one account forging on 2-3 servers at a time, and the servers end up in forks independently of each other. And only the "correct" one is shown in lompsa.com, of course.
What might work better, could be that warmach and/or any other "too" large server split in two, dividing the balance between two servers. For a pool, it would require moving half of the forgers (balances) to another server. For starters, warmach could move his own balance forging to another (account and) server. Also the forging support from association could run on multiple servers (if not already running). What do you think?
*) I'm using the term fork here in a wider sense: any chain of blocks, regardless of the "correctness" of that particular chain in consensus of the network.
