Hey guys, here is a list I made for our local playgroup. The main (and only) goal is to be able to play with new SA models as they are sold, no proxying and no leftovers due to formations sizes.
So this dictates deviations from regular lists like sizes of formations (8 unit Russes), loadouts (no sponson Russ) and differences from EA units (Basilisk being better armored because SA version uses Russ chassis)
In 40k narrative this is supposed to be a regiment from an Armoury World, stockpiled with older tech and outdated patterns.
Imperial Navy planes have also been altered to fit new model range.

First version of the list in attachment and here is the link to online version:
