Regarding your house rule on AFV on crest line modifier on firing, do you mean the improved defense modifier?
Yes, that's the one, +2 to the dice roll.
Now I noticed that there's a similar modifier (but +1) for AP and ART fire for any kind of target on a crest line. I would apply the same principle there. First draft on how the rule could read:
Both the AP/ART fire modifier for Target on a crest line and the AT modifier for AFV on crest line have the prerequisite of at least one of the attackers being at a lower height compared to the target.
