I find the cannon-Stuka isn't so terribly hard to use. I like to set convergence at 1000m (So I don't have to get too close), dive in at 45 degrees (any lower, and I always tend to fly into the ground).
Although it's slow, it's also hard to spot at low level, so if you're sneaky, you can survive.
I recall on an a closed pit server some years ago that I was flying a Fw-190F at no more than 100 m AGL and I was even escorted by some spitfire after I dumped my bombs and blew up their artillery

The AB's were mostly meant for ground troops and installations, I think. Every time you see a tank in war footage, there are at least a few dozen infantry sitting on it, and running behind it and to its flanks. Soldiers also had to eat and sleep on the go, so I imagine it would be possible to find soup lines or camps with tents (maybe not in the open, but hey, the Eastern front had a lot of steppe). Obviously, this isn't modeled in Il-2 (the closest thing is the "field HQ" target in DGEN which has staff cars, and radio trucks parked in a city or treeline).
Anyway, Il-2 does have frightened truck drivers, so maybe these models can be repainted to look like soldiers, and spawn as a group to follow around tanks and trucks, or have their own way-points etc. It's already possible to kill fleeing drivers, so this shouldn't affect "gore" considerations.
With 4.11 you can adjust the time that AB's will start to fragment. You can practice with time settings and altitude to get the best results.
