It might be helpful to find out how large of a scale she was thinking of.
If it was built in microscale, it would be much more reasonable and time efficient. Did she provide any idea of a timeframe? I’ll think on this over the holiday and might try to put together a concept build.
It would be helpful to know how big she’s thinking. A 1’x 1′ model on a 32×32 plate wouldn’t be so bad…or is she thinking some huge model taking up a few feet worth of space? I suppose it depends what the purpose of the model would be.
