Soma Double Cross Updates- Ideas?

Hi all-

Thought I’d post here to try and get some advice/ ideas on this project. My vision for this bike has always been to accent the cream color with silver and tan bits. This was originally built up with an old Ulterga groupo from the parts bin, some shinny parts from Velo Orange, Brooks Saddle, Nitto Noodle bars, tan Salsa tape.
 

My project now is to 1) update shifters to the ‘under the bar tape’ type to smooth out the cockpit look. And 2) go 1X drive train. I’d like to accomplish this with an eye towards keeping the silver/ shinny/ chrome look, rather than the space grey or black components like GRX or recent Ultegra group.

Any thoughts or ideas here? Have ya’ll seen similar styled bike out there on the inter-webs? I don’t mind going a little ‘franken-bike’ to make this happen. I've looked at mixing/ matching XT cassette and derailleur with new Ulterga shifters (I *think* this would work) but that leave me with the front chainring issue. GRX looks nice but don't like the color combo. Older Campy maybe?

Some specs: Hub Spacing: 132.5 mm, Bottom Bracket Type: 68mm English

Appreciate any thoughts or leads on this project!
