This is a site for the preservation of Japanese swords, regardless of their era. You won't get any traction or support for your idea as is.
If you want to create such a thing, honor the history by making it from new parts and new materials, using their techniques. Not by mutilating a surviving veteran. This would be the proper way to realize your idea.
Regardless of your theories regarding cultural Stockholm Syndrome, it is well documented that such things as the Kyu Gunto were in fashion at the time of their creation. (As well as being seen as a way to catch up technologically with the rest of the world.) Much like things such as the creation of cloisonne fittings or Namban tsuba. Culture is an artistic expression and extension of what people find to be worthy of sharing, and as such, culture is shared and blended when it comes into contact with other cultures. People like and dislike things, but that is getting into the philosophical field of aesthetics, and one can easily spend years talking about that.
As said, if you want to create such a thing, leave the antiques alone. They are venerable survivors of a past era. Make it from new material!
