I'm not sure what you call "layer". AFAIK MBTiles files do not have a concept of storing tiles for different layers.

It is true that the spec doesn't say anyting about tile size, but are there MBTiles files with tiles not 256x256 ? This isn't supported by the driver. On writing this shouldn't be a big problem. On reading this might be a bit more tricky as you could potentially have a mix of tiles of different sizes !
