The one thing I would say is not to allow you to take the Infernus or Valdor in squads, they can go in Tericos but only as individual tanks.
In lore both vehicles are supposed to be very rare compared to the standard Malc. The Valdor has only just been invented as a dedicated auxilia tank hunter and the Infernus is literally a Titan grade flamer built into a tank.
It SHOULD be hard to spam them, not LOW hard but still relatively difficult you know?
As for the Veletaris Command squad, I feel like the vets are fine at WS 4 because they are only mortal at the end of the day, +1 attack over regular Veletaris is fine for showing their experience. Give the first prime WS5 and a rule which compels them to issue challenges and a refractor field (5++) because they're basically auxilia champion consuls just not as strong because again they are mortal.
All your other ideas seem great tho senpai.
