Though not what you are asking, this makes me think of another idea: Imagine being able to go back in time to someone else's dinner party, such that you are the only one who is time-traveling.
I would visit the Baron d'Holbach on one of the occasions when David Hume was there. His guest list was often impressive. See:
https://en.wikipedia.org/wiki/Baron_d%27Holbach
But if I keep to the exact terms of the OP, both d'Holbach and Hume would certainly be invited anyway.
It would be difficult to make a list for one dinner, as there is a problem with inviting too many people, because then one will not be able to hear all of the conversation. Beyond a manageable number, any more would be irrelevant, as one will not be able to effectively interact with them.
