One of my professors told me:

Nothing is ever perfect. You must always sacrifice perfection before a project is complete.
With the cheapness of Arduinos and Raspberry Pis, throwing a bunch of them together is always a potential solution.

EDIT: I'm not sure a CPLD could have stopped the use of the ULN2803, although maybe it could have replaced the Arduinos. If the Arduinos were good enough however, then no harm-no-foul really.
Its just that a CPLD can implement things like a 27-bit shift register over SPI or I2C really easy (assuming you have some Verilog or VHDL coding skills). So maybe you'd be able to do Raspberry Pi -> CPLD -> ULN2803.
