20K - A 15mm not-Tau battleforce for $55

The initial idea for this post came from an old (july 2011) article on Dropship Horizon about building armies from incomplete lines... 

Tau Battleforce (minus the drones) painted and photographed by Paul at theunrealisticartist.com,
all 15mm equivalent pictures from the manufacturers websites; 3 packs of Ygs, 2 of Meso Nai,
1 of  Gitungi, 1 Battlesuit and 1 Grav APC: $50 (add $5 for a pack of drones)

Chris used CMG Ygs as an example and proposed a couple of idea to turn that single pack of 5 apparently lighty armed aliens into a "battlefieldable" fireteam. It went along those lines:

• Call the helmet on one of those guys some sort of "C² interface" and that guy an officer;
• Consider the pistol sized weapons to be very high tech and very compact assault weapons whose capabilities rivals other species more cumbersome rifles or SMG;
• And consider the SMG sized weapons to be equally high tech and compact support weapons.

One issue remains though: the lack or variety. I would consider buying 2 or 3 of those packs to make a squad/section sized force, but anything bigger would be to much... So I took a leaf of the Warhammer 40K book and turned them into an high tech Alien Empire with lots of battlesuits and client species auxiliaries...

Troops

• CMG Ygs obviously operating in small high tech fireteams with compact high power weapons
• Khurasan Meso-Nai makes wonderful savage auxiliaries armed with a mix of bows and spears, or even mounted on giant birds and lead by either a shaman or a tribe leader in high tech armour (a "gift" of his Ygs masters)
• Another good condidate for a client species of the Yds is the wasplike Khurusan Vespulids...

Vehicles

• Just like Chris, I thing GZG High Tech Grav Vehicles are the perfect match for the Ygs... APC, Tank and MLRS would make a good starting combined arms force, with other option available like C² or PD...

Battlesuits   

• The spearhead of any not-Tau force is of course battlesuits: my choice for those would be CMG Protolene Khanates Battlesuits: they're available with a wide variety of arms (both CC and ranged weapons) and with various "backpacks" (comms, missile launcher, guns, mortar and if I'm not mistaken some sort of jump pack)
• The latest addition to this concept: Micropanzer Gitungi have just the right mix of GW stealth armour "facial features" and Yg stockiness... I just hope they're the right size to be considered Yg stealth PA without too much of a stretch!

Drones 

• Another staple of any not-Tau force, GZG has a pack of 9 Grav Mini Drones

Characters

•  Albeit physically pretty different from the Ygs, CMG Praesidentia Ancients could relatively plausibly (to me at least) be Ygs from a different biological cast and make good religious leaders/high value targets/VIP objectives...

 That's all I have for now... Thoughts?
