Nice use of the PI figures Commander.
Any chance we can see a piccie of these next to your other Halo inspired Humies (Copplestone Jungle troopers with helmet/head swops) from last year?
I bought a few of the Haloclix to try them out. They were cheap but really out of scale with any other miniature I would use them with. They are taller than most figures and slender. If scale bothers you at all you will probably not like them. I was very disappointed.
The Covenant are a much better option - they're alien and don't have the same "human-size" reference.
