I actually think that Kroxigor are pretty reasonable for their cost. They aren't Nurgle Ogres, but they do have a better Save and Strength. They aren't Trolls, but they are quicker and are easier to control. At S7 I don't think you can reasonably bring them down any lower than 50.
The problem, I think, is that everything good is in Special. Once you get 6-8 Kroxigor, which I'd love to run, plus a Temple Guard combat block (because you want at least two worthwhile combat blocks, right?), you've not got room for much else. Core, Slann, Oldblood, Scar-Vet, Skink Priest, plus 24 Temple Guard and 8 Kroxigor, puts you at 2.3k as it is, leaving a hard choice between Terradons, Camo Skinks and Salamanders.

Why not? Its a good lore for Lizardmen all around. You get easy access to it through cheap Priests and Tetto, the signature Spell has amazing utility, Curse and Harmonic are great buffs that really help Saurus, Comet is brilliant, and it has a bunch of low-level magic missiles.
