I kind of want to try this using an Impish set with full investment in bulk and run Belly Drum over EQ. Maybe Body Slam over Double Edge, and maybe Relaxed nature in a Trick Room team. Definitely want to Belly Drum somehow.I know you are much more advanced into this than me but I have to propose a Pokemon I use for my Streak of 32(I know, not a lot)
Double-Edge (tedious egg move you have to teach)
252 Atk 100 Def 152 SDef(<- obviously can be optimized)
=> It is simply a great check to pretty much all non-fighting special attackers in the tree. In case you are unaware, Gluttony+Recycle is pretty much a Recover for Snorlax, a move it wanted since Gen 1. I use it in Singles alongside Pheromosa and Tapu Lele and it always comes in clutch.
I bet it can be optimized even further!
EDIT: Ran some quick calculations and not looking as promising as I would have hoped on the physical bulk, even with 252 HP / 252 Def+. Might still work with proper support. A doubles team with Belly Drum Snorlax and Psych Up on a second Pokémon(ex. Mimikyu) would be pretty cool too if you can pull it off.
