Hmm, if there were sorta Xilinx chip that one could load with some CPU core (PIC, AVR, MSP...) into built-in flash, configure built-in analog modules and I/O's. If this bloody creature would be priced as low as PIC. To reverse the order of bits in one 100MHz cycle just load extended CPU core command set...
