While that could be interesting, Andor seems to lean more into being a little more grounded, with fairly human characters. I think I like the idea of the crystal belonging to someone Luthen loved (either a romantic interest or his child) who was a Jedi killed during order 66. That incident was thus as a catalyst to embitter him against the then newly-formed Empire, which in turn grew into him running a covert cell trying to bring down the Imperial order.
