I had a similar urge at one point and built what had been a singlespeed CX commuter into a 1x10 commuter with a 42t chain ring and I think a 12-27 cassette. It used a bar end shifter.

Eventually, it became a 2x10 again with brake/shift levers. These are the reasons:

I lost the chain off the front chainring a couple of times even though the chain line was good and the teeth were tall and straight.

I missed the big gears. I'd be going fast and then just think "oh well" as I spun out. I also missed the fine tune. It felt like there were a couple gaps where I was missing a gear combination.

Single chainrings don't look as pleasing to my eye as doubles. Doubles just look right to me, and I missed the appearance.

I was looking for a chain watcher so I wouldn't have to deal with a dropped chain on the way to work, and the cheapest options were front derailleurs. The thought of putting a front derailleur on as a chain watcher pushed me back into 2x10 land.

I'm happy there. There is symmetry. The cables make sense. There is no issue matching a brake/shift lever with a brake lever. There are no lone bar end shifters hitching a ride on one side.
