To add to the brain trust - I think a B2B would be possible at the new AUH terminal A. The 'arms' of the terminal are not very long and the transit security is in the middle of the terminal.
I stayed overnight in AUH and did OLCI. I was able to get through immigration and security with a 'print at home' UL BP.
FWIW the Pearl lounge is much better than the terminal 1 version, with one exception. Bring your UK style adapters if you want power. And be prepared to look hard for a power point - they are very few and far between.
