...but how will you then be able to fly in the UK ? (presuming that's where you are from) If you get an FAA CPL or ATPL you cannot then fly anything other than N registered aircraft in the UK. ..and as far as I know, if you susequently try to convert to a CAA or JAA licence, you will have to comply with the JAA medical... ..or have I got that wrong ?
You have my full attention if you have discovered a way around this !!
