I looked up 20cm as I understand inches more and that is 7 inches. I feel this will be too small for Snowy. I can see what you mean about wanting her to have more enrichment. I feel a wheel is the most important thing for a hamster so I would have the big wheel and shallow bedding on that side. I know you want her to have more bedding and enrichment but I think it is better to have a wheel they enjoy and less bedding then the other way round. That is just my opinion though.
