4 Armed Gen2 Synth Courser - Help Needed

[WolfmanMODS]

So the biggest single let-down of F04 was when I was fighting my way to rescue the runaway Synth at Greenetech Genetics and noting the deadly efficiency with which something called a "Courser" was plowing through numerous heavily armed and armored Gunners. Having recently helped Danse fight loads of regular Synths, I was expecting something truly spectacular from a single Synth unit that could do so much damage, such as perhaps a 10ft tall Synth version of walking sentry bot with a built in mini-gun!

 

But NO!, Courser Z2-47 was just a regular "Human" NPC model, and was just wielding a single standard Institute Pistol too boot, and I was significantly underwhelmed :sad:

 

I would subsequently like to fix the underwhelming factor of synths Coursers by re-designating all existing Courser as Infiltration Courser units and then create a second class of Assault Coursers that will be Gen2 synths in extra heavy Synth Armor, and for the kicker, they will have 4 arms thus allowing the Assault Coursers to carry two weapons at once!

 

 

 

So where I need help is figuring out how to make an NPC model based on the Gen2 Synth one that either has 4 arms and can dual wield as I would ideally like, or has something like a built in sentry-gun, that shoots independently if not readily possible. Also of note is that this will be an asset for a larger overhaul mod, so if this sounds like a "fun" challenge for someone, by all means make this as a mod yourself and send me the link so I can include and give full credit.
