Putting certain kinds of programmable logic on die is a very useful idea if done right. Unfortunately most people think programmable logic is only useful if directly exposed to or part of the user ISA. This has already been done in Xilinx Vertex reconfigurable PowerPC cores, Xtensa, and various research projects, but none are general purpose CPUs.
There is a far more practical way to use FPGA-like reconfigurable logic on a modern microprocessor executing a well known traditional ISA. Use your imagination if you want more details, since I really can't say more at this point.
