Possible, but not practical. Flash has a limited lifetime on writes (10k to 100k, depending on the technology). Even if writes are load-levelled, paging on such a storage device would drastically shorten its lifetime over what you might expect.
Most OS's allow paging to be disabled. This may or may not be acceptable for your use cases / applications. We had to go this way for Flash-based storage used in In-Flight Entertainment applications.
