How bad is this idea, I have black templers as normal vanilla marines + Liberians, cool 1989 metal versions I found in a chartity shoptrash I volunteer at + terminaitors and marine demi sqaud

all free!
Idea is
IG back up force, to support marine task force, artillery, infriantry, armour, filling in gaps n more bodies to block the holes. Basicly as by fluff they feth the codex on daily basis by there numbers, what's raising a regiment of back up troops, providing extra firepower n support.
Its a long term project but already designing my urban cammo on cheap push fit cadnians.
