In the Volc/Heatran discussion, I did say that Volcarona was viable, if you read through the posts. That wasn't what was being contested. It's Heatran's viability. I do agree with you that Heatran's resistances are a huge point in why it's viable, along with Flash Fire, with both of these being able to carve out a niche for it. Anyways, I'm not gonna talk about it too much since most of what I have to say was said already in my previous posts, but Heatran isn't outclassed by Volcarona, as they both have seperate functions (ik you didn't say that it was but that was what the discussion was about). In terms of stall's viability, I don't think stall is very viable. Double-targeting, spread moves, and the ability of a partner to take care of mons that would normally wall one pokemon all lend to making stall significantly less viable. I think that the closest you can get to stall is bulky offense. If you don't have a way of dishing out damage when you tank a hit, then you're just going to get smashed through the next turn, since you won't be dealing notable damage due to the decreased viability of entry hazards (although SR can work well) and the fact that your moves will be hitting for a lot lower damage than their moves You could try Toxic-stalling, but usually trying that ends up with your Pokemon dead due to getting torn through by the opposition, since that takes way too long to work.
