Duncan, those are somevery lovely and inspiring figures, but I am afraid that Tge Grey Ghost is asking after Warzone conversions, and those are Void models.

Grey Ghost, the Warzone plastics are eminently customizable, even if the plastic is a little harder than the usual stuff. I ve taken a saw to some of my Imperial Regulars and removed the arms and shoulder plates, allowing them to be replaced with, say, Cadian arms. They are very mutable figures, and to my mnd there is little you cannot do with them. The price ain't bad either.

I don't have any pics of my own conversions, but if you do a search for Warzone on this very forum, and maybe at Dakka Dakka as well, you should find some examples of what can be done with them.
