Most of the people helping Ady via the miracle of the magic internet tubes don't live in the UK so if you have some particular skill, idea or anything to offer you never know it might be just what he and the team are looking for.

As for the memory wipe only Threepio has that in the current version and that's because he is a motor mouth.

Even in the OUT he was a bit flaky about remembering Princess Leia which suggests he had some sort of block put on his memory.

I can imagine both playing a reasonable support role, maybe not as prominent as in the OT but enough to be recognisable come Episode IV should someone watch them in chronological order for the first time.
