Sunrise would probably decline the job given the lack of interest of the people in charge. "If you want to make money, you should probably treat it earnestly and seriously" was a saying that his mother (who he does not mention much, probably for not standing out as much as his father) would often say and he would probably see through the facade of easy money over harming your own legacy.

Would say there is a very good chance that he would be dumped out of the project even if he chose to stuck around for insisting that things are properly respectable. The only type of movie I can imagine Sunrise sticking around with would probably have to be something akin to the Iron Claw, a movie that treated its subject seriously and presented a rather realistic version of events without any major sugarcoating. He is satisfied with his money and probably would not bother with a cameo for his own ego's sake.
