Some people use the EPCS flash for non-volatile storage other than storing FPGA images. For example, you can still access the upper half of the device to store configuration data and such. You just can't boot from those locations.

The size of the file does not really scale linearly with the fit percentage. I would count on a minimum compression of 35% of the uncompressed files size (2.119 MB for EP2SGX60). Most likely you'll get better than that. So you could say 1.5MB as an upper limit but It may be that you remain under the 1MB mark.
