The EPCS4 is very expensive.

The EPCS device is simply a re-branded SPI flash. You can use devices from Numonyx and Spansion in place of the EPCS devices. Search the archives for other threads.

Is it feasible to read bytes from the EEPROM and use another pin from the microcontroller to produce the data[0] bitstream? (Other microcontroller pins would produce/read the other necessary signals)

Yes. Its a pretty standard method of configuring an FPGA. Here's some notes on how to do it with another FPGA or CPLD
http://www.ovro.caltech.edu/~dwh/carma_board/fpga_configuration.pdf But bit-banging with a microcontroller, or wiring the SPI port to the FPGA could be used to achieve the same thing.
