tips on making a converted haemy?

I have two haemonculi and both are heavily converted, one is actually the old metal archon from 3rd ed. I want to know what a good model is to use for a haemy conversion. I was thinking of using a wrack with bionic legs. Ideas?

Wracks work perfectly in my opinion. Take a look in my project log, you can see one WIP there.

I have a Haemonculus (or rather 'Haemonculix') converted from a Scourge. She has the double arms from the Wracks and an enlaged spine and tail made from a Cronos tentacle.

If you need any inspiration here's one of mine.

also the box of Warmachine Drudges (which work great for Medusae) also come with a very haemonculi solo you might be interested in. Great box price.
