Perfect Agony Seismic Trap with new Trypanon combo - build concept (20mil dps on mid-budget)

Hi. I dropped Skin of The Lords on SSF with Seismic-appropriate colors as well as Perfect Agony and that got me thinking if you can actually make it happen with the new Sandstorm Visage + Trypanon + Marylene's Fallacy combo.

Here's the PoB I came up with https://pastebin.com/NPDN0fAG - I started with Tripolar Bear PoB and worked from there.

I simulated Sandstorm Visage effect by adding "+95% spell critical strike chance" line to Trypanon, as PoB doesn't calculate this mod yet.

It has 20 mil dps (23 mil with flasks), defenses are similar to normal Seismic Trapper (100% Spell Suppresion, Eva/Armour). I used pretty much perfectly rolled rares to solve res and strength issues but those are probably not that out of reach considering various method of crafting exists.

I plan to try to roll it, but as I'm in SSF I'm still lacking couple of key pieces (notably Empower and Marylene's Fallacy). If anyone has any idea how to make it better or want to test it, that would be awesome, I don't really know the poison stuff well.
