If you are keen to do the midjourney discord you can find me here and upscale everything you like 2x and 4x as I usually do not bother to do so (maybe I should 🤣):

This is an example of the 4× upscaling although it is not as detailed as magnific. I assume magnific is trained specifically for that. I am more interested in the pic to video enhance at the moment and trying pika.art as the midjourney one is meh for now.
