A couple issues: First off, just because you have been DOE for 10 years does NOT make you an ansi 3.1 SR HP, depending on what exactly you have been doing and where. Secondly, you will have zero quals in Pads, so wherever you go you will need full OJT/TPE.
Lastly, will be security.. you will need an initial PHQ, which will include MMPI, fingerprints, etc... These are issues working against you. Good luck.
