It would be very complicated. Along the edges, pixels are partially transparent, so the frontier between two tiles is the overlap of partially transparent pixels, which is never totally opaque. So you have to either cover-up the mess (like what is done with the unescapable 1px) or devise an algorithm to figure out which edges should be made of fully opaque pixels (and handle vertices pixels appropriately).
A possible shortcut is to get the mosaic with joins as little intrusive as possible (color and thickness):
And then apply a small "Median blur" to the picture:
