I am also interest as well I try to complete files with German WW1 aces who also flew as pilot in WW2. Well known is the Hans von Hippel, who flew as fighter pilot in WW1 and have few air claims and in WW2 flew on controls of Ju52. I know that this is not modeling site but maybe somebody would like model of his Albatros fighter:
