On an extended thought: I feel like the Tongs result is a pointer in the right direction, because between it and the nature of Altdorf it raises the question of whether you could make an interaction between winds without trying to have one touch another close enough to form Dhar.
It's simple really: If you can't control the other wind yourself, just get someone else, or with an enchantment something else, to do it for you and build your efforts around that known quantity.
Then you have no one wind manipulating another, just getting several spellcasters with a good working relationship, letting each control their own contribution, and seeing if you can get something out of their combined efforts that's more than the sum of its parts.
Though, honestly, that's... basically just Windherding. Or at the very least, a subset of it we're likely to learn quite early on.
While an interesting idea and something i'd be interested in actually doing. It would require collaboration with some other mage to manipulate their wind alongside our manipulation of our wind to try and do research into mixing magics to create something else which is oof since i remember the idea of theorireticlly it being possible for if you managed to gather 8 mages of their respective colleges to all cast in tow together then they'd be able to create Quaysh but in turn you'd have all the mages rolling dices individually for a fuck up and that's basically a nightmare waiting to happen.
Not counting that said partner would require fine manipulation of his or her wind, probably does not have the same cheat as us to dispose of any dhar generated and would rely solely on the room we just used to nope any dhar generated, and such research is still very questionable to mages at large at least to the colleges stance on it even with our safeguards so we'd need somebody who we could trust to do such research with and even then, some of the knowledge we would use may have said mage were collaberating with question where we could have gotten it from which is dicey.
It's something i'm interested in to say the least, but the idea of needing more then one mage to cast a specific magic is one that seems to run into the issue of each mage needing to make dice roll to see if they succeed on their part which is oof, dicey as seen with the theoriretical example of creating Quaysh if you gathered a mage from each respective wind college to cast in tow to create it which is a disaster waiting to happen, at least with enchantment the consequences are reduced unless we roll hilariously bad.
Only example I can think of in quest lore of multiple magic users working together to create something bigger then what they would be able to do alone is the dwarves and elves working together, and even then it was only in artifice they managed to combine their work, not wind magic it's self of the elves unfortunately. Rituals may be an exception to this rule though, as I don't have the quote but i'm preety sure unless my memory is failing me Boney said somewhere sometimes rituals require other winds to work although not sure if that was him mentioning it in reference to components in the ritual requiring different winds in them or the ritual it's self actually needing wind's to some extant being controlled or channeled into it.
Either way, as long as chance remains with wind magic, then arcane artifice is going to be the limits of combining multiple magic user's efforts unfortunately unless we encounter something to make the dice kinder to such efforts which can be translated on large to the rest of the colleges like say a god of magic and even that's dicey in how it would be received on large and the God in question.
Either way, some speculation I wanted to add to the thread. hm, now that I think about it oof then, the plausibility of multiple mages to cast wind magic is preety low then beside ritual magic.
