Upgrading Imperial Guard Stormtroopers' Chimera: turret conversion

Sad accident for Imperial Guard Stormtroopers' Chimera. Its turret falls to the ground and now it needs a upgrade.
My Stormtrooper Chimera is a heavy conversion, made by many metal pieces from old Predator Annihilator tank. Build 12 years ago...
Here the pic:

Tank crewman has the head from Exterminator crewman (3rd edition, Catachan), Sly Marbo pistol and Chimera crewman torso.
You can see metal track guards and armoured skirts. I was playing Warhmamer 40000 addon Cityfight and this is Stormtroopers' dedicatet trasport. Once upon a time my stormtroopers has the crewman color scheme...

Let's start upgrading Chimera turret:

I remove pistol and smoke launchers. Stormbolter magazine now looks like better...

Stepladders and round hatch.

Chimera turret assembled with twin-linked Heavy Bolters, armoured plates and Hunter-Killer Missile Launcher. Twin-linked Heavy bolter (like FW Ryza Chimera) because Stormtroopers need a lot of suppression fire, they cannot waste their personal fire against light infrantry.

Green stuff work....
