WK Dwarf sallet helmet conversion

Someone was asking about the possibility to do a unit of WK dwarfs that are all wearing sallet helmets. The big obstacle to using all the available poses is that the WKD-03 set (action poses) have heads that are cast on to the bodies and 3 of the 4 are wearing floppy hats.

So I went to task to see how hard it would be to convert one with a spare sallet helmet. I took a pair of heavy duty metal cutters to the top of the head on the figure (just below the hat) and did the same with the beard peaking from under the helmet. This was followed by some more cutting with a hobby knife to remove the excess metal on the top of the head/bottom of the helmet and then a lot of filing to get a nice flat surface (head should be filed back to just under the nose). The bottom of the sallet helmet isn't completely flat, so a small gap remained on the front and the back, but a tiny amunt of greenstuff  quickly filled it. I think I spent about 20 minutes on this, most of which was filing away at the parts. It didn't even occur to me to get out my dremel, which may speed things up.

Anyway, I think the result looks pretty good and I'm now considering whether it might be a good idea to give the same treatment to the other 3 bodies and throw them in a mould for more variation.
