Yeah, that's a cracking idea.
I love the idea of a skellie pike block!
Good idea to have them open-handed - players can then choose whether to have spears or pikes and it means that wire weapons can used instead of either bendy lead ones or ones as thick as a telegraphy pole!
Not sure about the hat, though. You're right, it is too big, but I also don't like the style either. The occasional helmet wouldn't be bad though.
And as I looked at the models I kept thinking one thing - where's their necks?
Humakt- thanks for the feedback. That's the joy of kitbashes, you get to discover for both good or ill, without paying to have a green sculpted. As for necks, I think it's just the angle of the shot. They do have them
You can see them on the halberdiers here. Those skull are heavy, without having much muscle to hold them up.
