If Servers Merge what about xtra Toons?

[KelticKope]

To explain more, in the event of Teal and Green re-merging.

What happens if I already have 8 toons on Green and 8 Toons on Teal?

And Further more what about much later when everything dumps onto Blue?

And please don't get me wrong, I am for both eventually, I love the idea of everything dumping onto a set server after a 2+year cycle, and the "green" server restarting fresh.
but I am curious and concerned about this.

Obligatory, I apologize if this has already been discussed, I have not seen it.
