The Heralds on Ashyn did have access to Surgebinding, granted to them by Odium and Honor. Their Surgebinding was unrestricted and similar to Microkinesis, but was not Microkinesis. I would argue that the Nightwatcher does not have to have Honors power as Odium is capable of granting Surgebinding on his own, so there is no reason why Cultivation should not be. 

Your right that Odium can grant Voidbinding/Surgebinding, the one exception to this is bondsmithing due to the lack of adhesion. Yelig-Nar is a unmade Odium whom Odium gave the power of every surge however adhesion was a exception to this because that's Honor's surge. Cultivation could replicate tension but I think that they probably got Honor's help in granting the Nightwatcher adhesion.

I don't think we know enough about why Honor can give access to adhesion but not Odium to say for certain whether or not Cultivation would be able to.

The favorite thing for some of the Shardcasters seems to be the line, "Honor's truest Surge." We still have no idea what that means.

But again, Ishar was a Bondsmith on Ashyn. From Syl's RoW interlude:

"What do you know of my powers?" Dalinar asked her.

"Your abilities are what made the original Oathpact," she said. "And they existed—and were named—long before the Knights Radiant were founded. A Bondsmith Connected the Heralds to Braize, made them immortal, and locked our enemies away. A Bondsmith bound other Surges and brought humans to Roshar, fleeing their dying world. A Bondsmith created—or at least discovered—the Nahel bond: the ability of spren and humans to join together into something better. You Connect things, Dalinar. Realms. Ideas. People."

And we know he and most of the other Heralds were followers of "Passion" at the time, with Ishar himself being the first Odium convinced:

The Stormfather paused, then rumbled more softly. I never liked him. Though I was only a wind then—and not completely conscious—I remember him. Ishar was ambitious even before madness took him. He cannot bear sole blame for the destruction of Ashyn, humankind's first home, but he was the one Odium first tricked into experimenting with the Surges.

But on Ashyn it was Odium who had given power to the not yet herauts?

we know that Honor gave power to Nale and Only Nale

(Wat ch64 “Nale,” Tanavast said. “It is good to see you. Tell the others. Did I lie to you last time?” “No,” Nale said. “But the powers you gave me… they helped burn the world itself.” ) 

who seemed at war against the others and we know that a bondsmith (Ishar) had to guide them to Roshar, in the flashbacks of the creation of the oathpact Honor tells them that he will take back their surges and retuned them:

(Wat ch64 I will take back your Surges, then grant them a new, and together you will become a force that both protects Roshar and binds the enemy away from it.”)

everything leads to believe that Odium gave in Ishar on Ashyn the bondsmithing 
may be the fact that Honor is installed first in roshar reserves him access to the surge of adhesion (or restricted it on Roshar)
or Odium fears that someone could simply use it against him after Ashyn Events

[ParaTulip fae/faer (declines as she/her)]

Maybe not creating Adhesion Fused was part of the math that went into making the Unmade? Could be that it would simply be more difficult for Odium to enable that power by whatever unit of accounting the balancing rules Koravellium came up with.
