Well... ummm... *I* was thinking of making my own CPU
so that no one would be happy.  Yeah, that's the ticket!

:-)  :-)

Only slightly serious:  this is actually possible now with 
the complexity of FPGAs.  There were a series of articles
in Circuit Cellar within the last year where a guy described
how to do this.  You could (in theory) pick your favorite
parts of every CPU and blend them into YOUR favorite CPU!

Reality is - it's much cheaper and easier to just pick one
that's available that you like and go with it.  Currently
I'm using a Motorola 68HC12 (and HC11) but the fairly new 
Texas Inst. MSP430 family is looking more interesting as I 
look further.  (esp. MSP430F149 - 60K flash, 2K RAM, internal
clock oscillator, 8 channel 12 bit A/D, very low power, 
EXCELLENT CPU architecture, Timer I/O that's better than
the HC11/HC12 (but not as good as the Moto TPU), 8MHz, 
48 I/O pins, about $4 or $5.)
