lets go for the last one:
warning, havent tested it really, but perma SB is tested.
with an essence, blessed aura, glyph of swiftness and an 20% enchant mod you can keep up spell breaker forever. <---- epic typo was here, now its gone
add or spirit bond and prot spirit, or prot spirit and shielding hands and its hard to die, really hard
the math( o_O )
SB got an recharge of 45 secs, we got an essence and glyph of swiftness:
45 / 1.2 = 37,5, 37,5 / 1.25 = 30
so the recharge of SB is 30 secs now.
@ 16 prot SB lasts 18 seconds, but we have an of enchanting mod and blessed aura makes SB last 37% longer.
if you have an +1 divine 20% staff its 38%
so 18 * 1.38 = 24.66, 24.66 * 1.2 = 30.24 sec
i tested it in UW and it works, perma SB
if you add shielding hands you have it perma to:
recharge = 15 % 1.2 = 12.5
8 * 1.38 * 1.2 = 13.24
as you are an ele secondary already you can just use sliver armor for damage, maybe use Stoneflesh Aura instead of shielding hands.
add Balthazar's Spirit and as long as lots of things attack you your energy managment is nice to
i guess for some areas you wont need SB so you can add something else, and that can be an elite skill for nice damagewith elite skills like RoJ and shield of judgment.
becouse PuG's wont accept a monk for wastes or pits i havent testes it a lot.
but i think with the right tweaks you can use monks and do a fairly fast UWSC if SF sins get nerfed.
and the good and bad things of monk UWSC builds:
Good:
you dont need full cons, just an essence is enough as +100 health kills you, but armor of salf is nice with + health regen
nice energy managment with baltazar's spirit
shock wont deal a lot of damage to you.
most traps wont hurt a lot.
no 33% less damage becouse you dont have SF
you dont need max armor so mobs are more likely to attack you and not the vale necro

55HP monk + illusionairy weapon = LOL
a 600 monk with pain inverter would be fun

Bad:
you need at least 5 slots to be invincable, SB blessed aura, glyph of swiftness/arcane echo, prot sprit and shielding hands/spirit bond.
not so much skills left for damage or utility like i am unstoppable.
need to recast prot spirit/healing hands a lot, so slower.
if doing pits, aoe degen kills you, so rampaging minions are really bad.
flame traps are nice, O_O burning would hurt.
so think about it, would it be possible or not?
critic is welcome, and ideas even more

//edit//
some things to stop some flaming:
if its possible to do UWSC with 7 monks instead of sins i think it wont be record breaking.
i posted this becouse about once a month i have a good idea, and i think this is one, adn there are a lot of people on this forum, so more good ideas, and with 100 good ideas this can get good

and there are a lot more monks than sins, if some areas are not so hard and quite fast as monk monks can do UWSC to, and more pople doing UWSC less time waiting forming a group.
