Isn't the Spartan a little overkill for this kind of application?
Although the low-end chips in this family are about $10 in single
quantities + $3 - $5 for the config EEPROM.

The Xilinx XC9500 CPLD series might be a better choice. It's available
in smaller configurations, it can handle 3.3 and 5V I/O, it's flash
based so you don't need the external EEPROM, but it's still in-circuit
