Ciao Devon, quick answer, andrea will provide more. We have implemented something similar a few times in the past for clients specific customizations so we have a pretty clear idea on what to do. First thing, GeoServer is already able to mosaic raster in different CRS but at an higher level, inside the streaming renderer which leans onto the streaming renderer for reprojecting.
Bring this at a lower level is challenging if we want to keep both performance and quality or at least if we want to be able to control them. If I had to suggest something right now, I would suggest to group them by source CRS then mosaick them and then reproject each mosaic to the target CRS so that raster data in the same CRS with different resolutions can be handled separately. Let's see what andrea says... Putting this on the table upfront, don't come up with a PR that will touch 1k files (i.e impossible to review) without having discussed the approach before because it will hardly be accepted. No intent to be a showstopper, I'd like this functionality to get in but you are biting on an hard candy trying to implement it.
