The low gear is important. Your 20 speed system has a large range, even larger than most 1x12 setups. 1x11 gives a little up. You get to decide which end. 22/36 is about the same as 28/46, if you match the low and sacrifice the high.
I think I’d rather have the Sunrace ratios than Shimano for 11-46.
Velomine has the Box groupset on deep clearance right now... if there’s any left
