Has anyone tried running a neon transformer in reverse to step the voltage down?
To the point: is this a completely stupid/dangerous idea?

it's not dangerous and it works (but for small power only)

Not at all stupid. In fact, thats what potential transformers are, although they do not have the internal current limiting shunts that NSTs typically have. With potential transformers, you basically would put in the high voltage and then its divided down to a monitoring voltage that is compatible with low voltage test equipment.
Of course, the real question is why would you ever want to. 120/ 240VAC is readily available from the outlet.
Potential transformers on the otherhand are run in reverse as step ups! So that 14.4kv:120VAC is run in reverse to provide a very reliable high voltage output for medium sized tesla coils!
