Can I make HP and SH work together?

what if, Harry Potter Universe and Shadowhunter Universe existed in the same space? Bear with me for this particular brainfart, please. Okay, so let's say, that way back when, when the shadow world wasn't yet the "shadow world", but instead was more interwoven with the regular humans, some of those regular humans would develope the ability to weild magical power, due to being exposed to so much supernatural energy all the time. It was mostly the friends and family of downworlders. As the shadowhunters were full on power tripping then and on their racist superiority shtick, the warlocks and seelies banded together to create a pocket dimension for the magically abled humans, where they would be able to learn about magic and safe from the same persecution the downworlders faced. For the first few decades, the warlocks specifically had a hand with helping the new wizards and witches to build up their society, learn about the magic they were able to command, and came up with the focus instruments (wands, brooms, potion brewing equipment…) that made it possible for the humans to control their magic. But as the years went on and the magic humans grew into their power and world, and the world at large grew into the distinction between a mundane and shadow world, the warlocks and wizards came to the mutual decision to leave them to govern themselves and their magic dimension. As the warlocks didn't wish to rule over the wizards and witches, and also they did kinda have other things to worry about, with the shadowhunters still hunting the downwolders and all. The wizards agreed to keep their magic hidden in the mundane (or muggle, as they came to call it) world, lest they get targeted by shadowhunters or demons seeking magical energy. So the years go by, and each world develops on its own. However, the day that Magnus learns what has been going on in the wizarding world, courtesy of two boys driving around in a flying car, he gets involved. And with him, the rest.
