I took a couple of photos and stuck them on Flickr with my Canon T5 (1200D). I took this picture using RAW+L to get a RAW & JPG image, and then compared the two. If you zoom in, you can see there's quite a bit of mosaic on the RAW version, even though I took the slider all the way to the right.

I've tried a variety of settings but it doesn't really appear that I can demosaic my image that much.

Is there some combination of demosaic and other effects that will get my images a little less... mosaiced?

The differences between the two images aren't due to any particular mosaic or demosaic setting. It is due to the way the camera's jpeg engine is interpreting the information in the raw file compared to the way whatever raw editor you are using is interpreting the information in the raw file based on a large number of settings you have selected, none of which are named mosaic or demosaic.

If you want to apply the same (or nearly the same) processing to a raw file that was applied to that file by the in-camera processing, you can try the raw conversion software provided by your camera manufacturer. Most of them will even open a raw file using the in-camera settings at the time the image was created. Most third party raw processing applications ignore the in-camera settings when opening a raw file. Instead, they use whatever default profile has been selected in the application.
