Solaria isn't that far off. Our 17 nobles are just shy of 10k, and we are currently refitting. Of course noble count isn't all that matters. Not that it is the most relevant number, but in terms of total economy Solaria has 3k to their 4k.
Noble count is not the determining factor in my opinion anyway. I think gold is. Pian en Luries has very close to the amount of gold income that they do (Auvrendil?, spelling probably wrong) but could never hope to field even 15-20k cs.
