No chance. For hundreds of bales we're not talking a little extra headroom or anything, for them to be truly dynamic and responding to things around them properly you'd probably need a second dedicated GPU just to process the physics.
Even basic dynamic objects are horrible performance *censored*. When BulletBill was making The West Coast for FS17 he had a lot of dynamic objects (objects which can be moved such as pallets and other decorative or junk items) but when he made many of them static performance improved massively. For proper bale physics we're not just talking dynamic objects (bad enough, hence the bale limit on consoles), but also where each of them can deform individually (like tyres do with weight).
