I started making something like you're enquiring about for war engines in EA (no such game as Net EA btw, NetEA is just the lists, EpicUK, Epic-FR, EpicAU etc all use exactly the same ruleset, the Epic:Armageddon rulebook from 2006 or so

)
basically I had a nice pic of the war engine and a summary of its weapons, and an area to mark shields/damage/crits like warmahordes cards use, unfortunately real life got in the way and I've not managed to get any further with it....
here's a mockup of one for a warlord titan, still needs more work, the idea is for them to be ~A6 size so you can laminate them and use dry erase markers to write on them

when I get some more time I'll look to push this further
