If I were going to fix R'lyeh, I'd give them the ability to recruit enslaved sea-trolls (capital only), and do something to make all those free-spawn atleast somewhat effective offensively-like make a level 0-2 national spell that makes them all slightly poisonous (1 point of damage).

It'd also be nice if the sacred aboleth recruitables had a counterpart to the Mind Lords

As far as national spells-I'd do spells that summoned Polypal Mothers who could produce stronger types of spawn-one that's amphibious, another one that has weapons-grade (low level) life-draining, a third that has mild poison, a fourth that can "fly" underwater", and a fifth with slight regeneration, and maybe a spell that "mutates" all your troops into more effective forms-give them one point of (improveable) Un-natural armor or a water-version of Breath of Winter or Moss Body (can that be cast underwater? I'm at work) or makes their natural attacks armor-piercing, without increasing the damage, or makes them all sacred-since sacredness probably is different for an Aboleth than for a human. I think that would be neat. Naturally, these spells would be tailored to be cost effective when you use them on masses of spawn, but very inefficient for any other use, for balance.

Please Note: some of these ideas, I'm actually using for mod nations that I'm working on, but my wife and I are in the process of buying and moving into a house, and I have neither the free time nor the concentration to get them out any time soon, so feel free to use these, I just might come back later and use them myself.
