I've been toying around with a thought, although it may or may not be legal, depending how you read the lizardmen faq (is Horned one a magic item or not). But I'll say it anyway.
Make your chief be the bsb and give him the skavenpelt banner. Then put him in a COC unit with FC. Then add two saurus characters in there, so that skink cheif can go to the second row.
Now you have a unit with two really strong characters on a mount and with frenzy, so a scar vet would hit 5 times and your oldblood 6 times (or more with magical weapons) and the command group would hit 10 times, and additional 5 attacks from second rank. With two scar vets in the unit its 25 attacks or with two oldbloods 27 attacks (depending on saurus characters gear). And thats not counting cold ones yet! When charging all thous attacks will be at str 5 or more (if you give your skink chief a spear).
The bad side of this the price. Taking a oldblood and a scar vet on a cold one with only light armor and shield, skink chief bsb on horned one with skavenpelt banner, light armor, shield and spear, and a unit of 10 COC with FC, it cost 852 points! Add to that is 100 points magical items for oldblood and 50 for scarvet plus magical banner for COC standard bearer, it becomes quite expensive. Not the most ideal thing to do but it's fun to think what kind of damage that unit would do ^^
