I feel you're going to have to get a new cage,or build one. Critter Trail cages and pretty much all pet store cages are too small for hamsters in my opinion, however making a 775 square inch DIY cage(even a bin cage will work)would be great.

Critter Trail cages can't be partially cleaned,since pretty much all the substrate will get soaked with urine and none will be saved.In my opinion it is too small and not deep enough to offer the benefits of a large cage with deep bedding,however just keep in mind if you do get a 775 square inch cage and have 6 inches or more of bedding that will make it cheaper and easier as well as make it much easier for your hamster to stay stress free.

Something to remember is that if you set up a 775 square inch cage right it will work nicely,but if it isn't set up well you may have to deal with behavior problems. A good example of this is not having many open areas,especially with new hamsters.
