Sure, if you've got enough of the right gates.
I tried designing a few CPU components on edge-connect cards, where they'd plug in to a backplane to make a complete processor. I overengineered them and ran out of 7400 chips, and that was the end of that. |

I'd say go for it. Make a very simple CPU just a few bits wide with just a few instructions. The experience alone will be worth it.

first step, the debugger...
using 16 leds and 16 resistors, enough to see what are doing logic gates... 
for the moment. |

cool videos. working on instruction set now, 8 bits opcodes, variable length instruction.
for the moment: 8 bits cpu, 8 bits data, 8 bits adress with possibility to grow. |
