I like the idea behind them, and with a different paintjob and no stupid grins or clown faces, I can see them looking mighty fine on the tabletop. I'm all for wacky, bizarre beasts in an Undead faction (one of my Mordheim warbands was an undead Carnival marching band, with instruments and all).
But, as someone said in TGA, they are capital G goofy, and serious minded people will need time to adapt.
When they released the "new" Imperial state troopers I complained for weeks about their moron faces, the lack of pomp and breeches, and the fact that some had ragged clothes or were barefoot. Now I love these quirks. It's nice when your Reikland regiment looks drilled and uniformed, while your Sitrland troops look ragtag and broke.
Also, the Mortarch and his liutenants... that's a very fine model.
