Hello!
I've been going through a 'what themed army can you get out the E:A IG army list' type-of phase, and I feel that what's missing is a sort of Elite/Storm Trooper type list.
I know that the 40k Vostroyan miniatures were a bit like Marmite - you either loved the or hated them (myself the former
) - I think the concept of a regiment of better armoured, disciplined & trained Guard has its appeal. Also, I think the current plastic Valhallan Epic Guard can be quite easily converted to look something like Vostroyans, with the addition of Green Stuff furry helmets (oo-er! 
)So I started playing around with the Guard list as is, and I thought that you could get something like this by taking one or more Tank Company formations, and support formations of Storm Troopers (sans transports) to represent Vostroyans.
The problems with this:
- limited command - I've found, like many others, a Supreme commander is essential for Guard armies for that invaluable activation re-roll;
- limited access to other support formations like Sentinels 'cause you've just taken Storm Troopers;
- and it's relatively quite expensive, so for a Tourney list you get fewer detachments and less activations.
So, just throwing out some initial thoughts about this list, I would propose a few things:
- Use Storm Trooper formations to represent Vostroyans, and exchange them for Infantry formations in the main list;
- Keep the formation size & stats largely unchanged, drop the 'Scout' ability, drop one Platsmagun for every two units and add a Heavy Bolter in their place (like the '1-in-2' Autocannons on Guard formations)
- Add a unit with a Commander, and up the formations value by 50 points
- Make a HQ formation for 450 points, with 5 Chimeras a Supreme Commander rather than a Commander.
In terms of other formations/upgrades, I don't see the need to change much; except dropping Guard Platoons (unless it's changed for 4 Storm Trooper/Vostroyan units), and maybe altering Fire Support platoons slightly to make them more Vostroyan like (e.g. 5+ armour, Heavy Bolters or Lascannons, higher points cost).
Okay, critique/alter/edit away!
Thanks for looking
