make prestigious, or "make important or influential" (António Houaiss, New Appleton Dictionary).
I have added your suggestion, and it will eventually be visible online.
But can we find a less ad-hoc translation? Some actual verb or commonly-used phrase in English? I can only think of the figurative "raise somebody" or "raise somebody up" (ie., to a position of importance). If anybody reading this has any suggestions, please contribute.
