I haven’t actually done it! But theoretically, if you have, say, a big folder full of 120 snare hits, with a dozen separate variants of each of ten velocity layers, then you could use DigiChain to create ten chains, one for each variant. Route a random LFO to sample slot, then route velocity to start time, and repeat for every other instrument in the kit.
I think this is such a niche use for the AR that nobody is ever going to offer this kind of detail in a commercially available acoustic kit, but if you have the patience and desire to execute on it, you could.
