WTD 1x silver crankset, Hollowtech BB compatible

So I'm trying to substitute this very nice but very heavy Tiagra, 2x, 10-speed crankset – with something lighter, more in fashion, as in 1x.

• Ideally I wouldn't need to change the BB fitted to my frame.
  
• Ideally, fitting one of @t0-ster's 110 BCD chainrings :)
  
• Ideally, in the EU so no faff with customs.
  
  

Thank you!
