It won't help too. We can use ASIC and/or FPGA if someone finds a software to convert this power which I wonder "how" and "when". If they found it, uses of ASIC and/or FPGA will increase in a great way.
An FPGA miner wouldn't help - but yes, programming an FGPA with the necessary functions would.. but it would mostly help in energy efficiency. Any modern GPU blows reasonably-priced FPGAs out of the water in terms of performance.
I'm wondering if reprogramming some used FPGA miner to generate vanity addresses will be possible.
