Can I have it back?
Exotic alternatives for Dura Ace could be for example Mavic or Superbe. DA7400 itself is very good though and relatively easy to come by.
Koga Miyata specced complete groupsets on their bikes, but sometimes, for example with the titanium FullPros, they specced Dura Ace with few 'upgrades'. To make it as little bit more special and save weight: Syncros cranks, post, stem and ti bottom bracket. Ringle skewers.
Downhill champ Greg Herbold raced Miyatas. He always specced his bikes with a lot CNC stuff in all colours of the rainbow.
It contributed to his flamboyant image. No doubt he still relied on Shimano for major drive train parts.
What you do is, next to the post, also taking a look at more stuff Heylight is offering. For example QRs.
Both the post and QRs you can have anodized in any colour you would like: purple, red, blue...
You could combine this with DA7400 and even silver Ultegra could be a clever option, due to better compatibility. This all will create a featherweight with great function.
Here a pic of the red Heylight I had made >>
