Update Desecrate / Detonate Dead Trapper to 3.1?

I've been looking over 1.5-2.1 versions of a Sab Trapper setup using Desecrate / Detonate Dead for some wicked fun (although a little slow and somewhat clunky). Unfortunately I haven't been able to find anything even remotely close to 3.0 viability and the upcoming changes to DD's AoE and 2 part damage with fire scaling. Any chance someone could help with a Path of Building tree, gem links, and gear selection? I've got a Fire Nova miner already, so I have some experience playing that type of style and some of it's gear / tree may even carry over.

I know there are current Scorching Ray CwC Deto setups but this sounds like it could be fun (though definitely not meta until 3.1 drops).

Thanks!

TREE:
Thinking about focusing on Elemental Damage, AoE, and Trap/Mine boosts?

GEM LINKS:
Trap/Remote Mine > Desecrate > Cluster Trap

Trap/Remote Mine > Detonate Dead > Cluster Trap > Fire Pen* > Chance to Ignite* > Increased Area of Effect
*based on upcoming 3.1 change

CWDT > Immortal Call > Increased Duration > Detonate Dead

Spell Totem > Detonate Dead

Blasphemy > temporal chains > x for second curse?

GEAR OF NOTE:
Tinkerskin (defensive choice) / Carcass Jack (offensive choice)
Sunblast Belt (to help with leveling, not intended for endgame)
Doryani's Catalyst ??

bump

anyone else have better ideas / input?
