I don't think there is any difference of doing a digital circuit 
"exactly as you want it" in an FPGA vs. doing it with TTL IC aside from 
the physical aspect, nor can you be any less adventureous with your 
ideas or (dis)satisfied with the result. You can also still do a 
streamlined and optimized board later on if it's worth doing. I notice 
you use the phrase "playing around" with some derision and I really 
can't understand why, as I'd consider that a positive aspect. By 
following your line of reasoning, we should probably make our own 
resistors, capacitors and transistors, too. Been there, done that and I 
really learned a lot from it - but I prefer to spend my time on 
something else.
