I think ultimately that's far too strange to be actually useful. As a concept it wouldn't go amiss as a IA-exclusive Mowang, but the Su-Jian would just be a unit designed to get close with a weapon that wants to stay far away and an operations theatre that doesn't allow it to use speed to maintain distance. Additionally, I think it'd be adding too much importance to the Su-Jian as a chassi. Plus, what you're describing is what the Kunai was meant to be if they weren't such awful shooters.
The Jingwei is very cool. However I'm trying to keep to the idea of what they can do with what they have now with almost no new troops. Though I guess I did suggest one lol.
I would like to see chain colt switch to riotstopper for Kanren. Paramedic for Celestials. MMR/MR Hsien join core link Celestials (hello Aquila in NCA). Move 6_2 for Crane please, they want to stick the pointy end of their swords to the enemy, you know? PH 12 (at least 11 or Dodge +3) for Pheasants - they have MA, this comes not from sitting on a desk. And remove the HD hacker. Linkability for Taowu (count as CG would be enough). ABH Haris Option (maybe only with a char) Sun Tze complete Rework.
