Is it realistic for Bowazon to tackle Uber Tristram or Ancients

I have a near fully kitted Bowazon for clearing Mobs with the only item I'm missing being Fortitude armor.

Is it possible for Bowazon to tackle the Ubers without it being a miserable experience, and I should satisfied melting mobs.

I'm happy to experiment unless it a well documented lost cause.

I've been collecting what I think is uber specific gear such as

Guillaume's Face and Gore Riders.

A few questions.

I have a lifetap

Wand. Do I need

Dracul's Grasp for the additional Open Wounds or would

Laying of Hands suffice with the

Wand?
I'm using a Act 1 Faith Merc. Will she just get melted where her

Fanaticism Aura is useless? Do I need to change to an Act 2 Merc?
Should I respec to commit more points into

Decoy or

Valkyrie to help tank?
Are there any other gear considerations I'm not thinking of?

A (phys) bowazon is certainly not the best suited for ubers since you're looking at (a) a bit of effort to re-gear into properly overstacked res for meph (with noticeably lower dmg as a result) and (b) a ranged penalty on crushing blow.

But it is absolutely doable.
