Hi Glenn,
I've had similar thoughts as you before. The Tarwar generally carries a reputation for being a tough user blade that can pretty much handle anything, but it doesn't mean it couldn't be "dressed up" and treasured as an item worthy of keeping and passing onto family.
If I were you, I'd pick up the phone or write Auntie Yangdu and talk about the options with her. She will give you some great ideas. Personally, I would go for one that has a double dragon carved red chandan wood handle or a dhar wood handle, thick brass guard, engraved double dragon blade to match the handle, and either Kothimoda style scabbard or horn/bone scabbard. It would look very sweet. I would also have a thinner blade version made to reduce the weight a bit for your purpose.
