The
ALLCAPS would be perfect for the role of ground AA for AdMech rather nicely; It's the same hull as the Macharius, and fits the theme of "Bigger and Heavier than thou" that the AdMech have going. Something like
WE DC2 / 15cm / 4+ RA / 6+ CC / 5+ FF / Missile Launcher 2x 60cm AP4+/AT5+/AA6+, 2x Hvy Bolter 30cm AP5+
Likewise, the
CAPSLOCK seems perfect for a Mechanicus troop transport. It would work as a Minorus with assault pod and "fast", but it looks so much like a Macharius that it really ought to be based off of that - something like
WE DC2 / 25cm / 4+ RA / 6+ CC / 4+ FF / 4x Hvy Bolter 30cm AP5+ / Transport 6 (Praetorians count as 2)
They are not exactly Ordinatii, as they have heavier armour and no shields, but fulfills the same roles. Using Macharii instead of Ordinatii gives the force a more "regular army with bigger vehicles" feel, where the Ordinatii gives an "exotic tech" feel; I think it is to the benefit of the list if both flavours were possible.
On a related note, the more I consider the Chimedons the more I like them; They fit well into the same theme as "heavier, upgunned" light transports.
