I wish
Even a dream list in jest looks weak. The SNES Mini fully embodies the generation it came from, while the N64 simply doesn't. Even the NES Mini only got appealing because of the 3rd party support that N64 doesn't have. It's the point where Nintendo became the provider for secondary consoles only, while PS1 carries the most important IP for nostalgia. And even among the handful of significant N64 games, many of them rely on goodwill from Microsoft - or worse. A casual N64 fan would certainly want to boot up Goldeneye not long after OoT... which is probably going to be impossible.
