... but even the best painting approach I know up to date, have troubles to convert them into something really enjoyable:
... but depending on your sense of humor, clearly there are other choices ;-)
Then, another option is using entirely different model. As for me the two most obvious choices are Terrorizers from Hitech Miniature...
... or Nurgle Plague Ogres from ForgeWorld.
real-world currencies, but give two clearly distinct approaches to twisted aesthetics of Papa Nurgle's children. Anyway, these are my personal choices ATM, but I'm not finally set on them, and still looking for alternatives. Thus, some other possibilieties:
Flesh Reapers from Titan-Forge are much cheaper and very interesting indeed, my solid third choice.
Crypt Horrors by Games Workshop are on the low-tech end of our gallery...
...as are Nurgle Bile Trolls by ForgeWorld.
The latter company has also two types of Renegade Ogryns, standard and Nurgle ones, which may fit into the role:
Scibor Miniatures has a range of fantastic Sci-Fi warriors which with very little effort can be combined into a unit of Mutilators. The steep price is however a problem in this case [in my case, at least].

(this Ice Arbiter has been painted by Alexi Z)
Finally, below are even more alternatives in no special order. They differ in style so much that should be possible to choose for virtually every army:
Incursion by West Wind Productions has a range of heavy infantry.
The Hosts from Troll Forged Miniatures are the fruit of recently finished Kickstarter campaign, and hopefully will be accessible for general sale in not so distant future.
Maxmini has this nurglesque Plaguebringer which is probably conceived as a Nurgle Herald alternative for Chaos Demons codex.
At the very last, a Warhammer Monster section at ForgeWorld has Skin Wolves and Fimir Warriors, which both are rather skinny, but may be took into account in this gallery of extraordinary characters...
Beside all these above, Pig Iron Prodution has Wardroids models, and Blight Wheel has War Bot, but personally I do not see them as good option, in this case.
I'm sure, there are other better choices which I overlooked or forgot. So, feel free to propose them in the comments. Thank you in advance.
