many will assume it's a whole new engine.
Not really, just put a read me somewhere that says the origin of the engine. And, anyway, the other derivatives of RobboLito/Ippolit (Fire, IvanHoe, Deep Saros) DID change the name of the engine. The only truly misleading engines were Houdini and Tactico that tried to deny the engine's origins.
This is how it works in the software world (kingliveson gave Linux as an example) but also in the computer chess world, here are two quick examples:
Glaurung: When a new group of programmers started working on it, the name was changed to Stockfish (though, it had the support of the original Glaurung programmer, I don't think Tord chose the new name).
Fruit: Was the fork of Fruit called Fruit 3? No, the name was changed to Toga and later Toga II.
Did Stockfish and Toga mislead anyone? Not really. Would they have misled people if they kept the old names? I for one, would have been confused if Toga was called Fruit 3.0, as I would have thought it was an engine by Fabien Letouzey, or Ryan Benitez, calling it Toga avoided any confusion or misleading.
So I think it's important to change the name.
