Your whole argument is based on mere assumptions. What makes you think nothing kakashi does will surprise Hiruzen? Kakashi surprises Itachi with clone feints, it was 30% chakra Itachi but that doesn't mean he's just 30% smart.
I don't see Enma touching Kakashi at his current speed, he can keep up with 4 v2 jins, what makes you think Enma is going to "own" him?
Saying "Hiruzen will be prepared for anything" has no backup support, If Hiruzen makes his elemental combo and he suddently doesn't see Kakashi there, what makes you think he would be prepared for Kakashi going out from the floor? Not even Itachi saw that coming.
Anyways I could say the same with Kakashi, he would be prepared for anything, since he knows Hiruzen is no ordinary shinobi.
When it comes to clone feints, Kakashi is superior to Hiruzen by feats, its the same when it comes to battle anallysis, Kakashi can make anallysis and provide a valid counter to the enemie's atacks, we already saw that against Pain, Obito, Itachi and Zabuza (on their 3 encounters). He would find a counter against enma, he's smart enough to know enma is very strong and fast (he probably would figure that out with a clone faint first) and then figure out that he has to keep long range and not get close to the monkey.
Kakashi, even without Kamui, beats Hiruzen.
Sorry It took me so long, was at work. Shall we go to war?

anytime he pleases (kishi). And kakashi would never see it coming till its too late.
Databook 2 - Henge Kongōnyoi:

User: Monkey king Enma
-Caption
Under a Nyoi/Staff form he assumes at will, Enma becomes Diamond (TN: or Adamantine/Vajra if you prefer) and bares his fangs!!
-main text
The third hokage's comrade in arms, the monkey king enma's transformation jutsu Characterized by the hardness of diamond and its at-will extensibility, Kongou Nyoi-Bou is Sandaime's"weapon of choice", so to speak and with it in hand he's made it through a world of war for an extended period of time.
Also, when Enma is transformed into Diamond Shifting Staff, it is also possible that he can attack out of his own free will, his claws and fangs add an element of surprise and irregularity. Forged in the fire of battle, its at-will transformation-based attack and defense go beyond the scope of proficiency, to attain the realm of Shinobi "godhood".
-picture comments
-The main method of attack consists in strikes and thrusts that take advantage of its extensibility. The hardness of diamond translates into destructive power.
-Enma's fangs assault the enemy!
And just like an elite 3 tomoe sasuke faced

, he cannot read unpredictable and unorthodox movements since a human can only do so much with 2 arms. Then on top of that What would kakashi Block Enma with? A small Kunai???...... Think about that for a second...
In terms of speed..

almost instantly no difficulty in old age.... Damn son! Kakashi has not shown speed feats that blow Hiruzen away. SO they are equal at best.
Taijutsu is about a tie, but add the fact He has enma goes to Hiruzen easily! Enma alone could Battle Kakashi and give him problems. You add the fact He could trap kakashi anytime he pleases.. GG?
Clones? Matched by clones! Kakashi's stamina is shit when it comes to shadow clones for battling. Add the fact all his clones would have enma shows even more.
Ninjutsu? Hiruzen>>>>>
Hiding like a mole? Sniffed out like

. Basically, if he tries to sneak attack He sniffs him right away since kakashi cannot hide his scent. And the fact that Enma can protect instantly makes that strategy null and void. When he tried it on Itachi, Itachi could sniff him out so don't bring Itachi up as if him and hiruzen have anything in common in terms of battling.
Basically all of kakashi best Feats are countered. But kakashi has no counter for Most of Hiruzen's arsenal.
Then you really think Fighting long range will be the best Idea? Let alone work? Really???....
