How that for a subject line, maright?!

So, I've got some Chaos Knight mounts with FW Nurgle Marines mounted on them. Not a terribly unique idea, I know (nods, with a flourish, to Thomas), but - frankly - I'm not crazy about GW's bikes, whicle I LUV their Chaos horsies. To complement my Ponyboys (stay gold...) I'm gonna do a Nurgle-ified Juggernaut for my CSM Lord to ride. Google it, naysayers.

My question is this: what're folks' opinions on the base for such a Jugger? I've got bike bases to put him on, but - frankly - they look pretty puny underneath him. I could leave him on the standard Jugger base, but are folks gonna beeyotch about a model being based incorrectly. I'm not talking about in "friendly" games at DL, wherein a sort of "I don't think anyone would complain..." kind of attitude would prevail (and - in fact - anyone who knows me knows that I'd just loudly tell haters to piss off anyway). I'm talking about elsewhere. Am I going to get dinged if - say - I take this guy to a tournament, DL or otherwise?
