The Dunamancy spells are largely weirder than Frost Fingers or even Create Magen. They haven't reprinted the spells from the Acq. Inc., Ravnica, and Wildemount books, and I'm guessing that this is because those books have their spells fairly closely tied with the products' identities.
I would love for this to happen, especially if they added more Dunamancy spells and more dunamancy subclasses (give me a Dunamancer Cleric or two! Luck/Karma-Shifter Rogues! Dunamis Sorcerers and Future-Self Warlocks! I want all of those!!!), but I don't think it's likely at all.
WotC does not own Wildemount, or the setting it is from, or any of the stuff specifically created for it. That is all owned by the Critical Role people and reprints or updates will come in their future books from their recently started publishing company. That is where the first book for Tal'Dorei is being updated and re-released.
