views paging dropdown
For now I didn't find any module for this but you can achieve this by playing around with pager CSS. Just like drop down menus. Pager also has an unordered list with ul and li. I tried it and somehow I was able to show pager as a grid on hovering it and it was working. 
You have to do some more in it to achieve exactly what you want.

Here I have given you a rough idea and I think this will help you.
