Uppercase "C" with slabs

[tobireif]

I really like Zilla Slab, but I'd like it even more if the uppercase "C" would have a large top slab.

Perhaps this could be added as alternate glyph?

With " large top slab" I mean something like this: http://www.1001fonts.com/maiden-orange-font.html?text=C (scroll all the way down to the "C")
