Do you mean a 20-46 cassette?
No
No
Like I said, you will be spinning big time, even up the steeps (and that can be counterproductive). But I guess it can be done. It might do ok on steep smooth terrain, but it will probably hamper you on technical ups where you need a little more torque. Edit: You can always shift higher out of the 46 if you need to. Personally, a 22 front with a 46 rear is plenty low and will likely reduce wear.

I tried a 22 on an 11 speed cassette. I think a 46. It was absurd. Like, the hill I could winch up with that gearing, that I could NOT winch up with a 28, 30, or 32T chainring on a 46T cassete is SO steep, and my speed SO slow, I simply flop over.
Sooooooooooooooooooo, I took that chainring off and never went back. I like 30, 34, and 36 depending on appliction. Tho I might give 28 a try simply because 9 is SO small in the back I can get away with it. I think a 9-42 cassette with a 28 front would be just peachy.
Though I am forced to admit that my 30 (or a 32) on a 9-46 is just way way more capable. I just don't ride on pavement to use a 30+ on a 9.
---------
If I biked 3x more than I do, and rode on pavement, I'd be rolling with a 34 on a 9-46 for sure. But just enough climbs suck on that that a 30 is the bee's knees.

reason I tried it BTW was that I was not convinced dropping from 27 speed to 11 speed was acceptable, reducing gear range from 540% to (at that time) 418% (11-46).
So I ran a 34T oval on my old crank like a proper 1x with a good chainline, and left the 20 year old 22T ring on the bottom that I could "manually" use by hand-moving the chain down. The chain was too slack and it was a 9 speed ring, but it was just for super-steep climbs to use for 5 min at a time, so it didn't really matter.
The conclusion? small waste of effort and massive waste of thought/planning. Total flop (literally), and if I needed the gearing, better to either go to a 30T ring or a 50T cog. Of which I tried both. Sometimes at the same time. Found that was PLENTY of gear range.
For me, a 30T oval + 46 cog is about perfect. Maybe one day I'll try a 28T oval on a 42.
I'll rock a 20T chainring when they make a cassette with a 6 tooth small cog. In the meantime, I'll enjoy real products

I run on my RSD Mayor
24T chainring
11-46t 9 spd cassette.
27.5 x 4.5 barbegazis at 80 rpm is roughly 16 mph in high gear and around 20 mph at 100 rpm. Fast enough for the purpose of this bike. This is a dedicated winter bike that runs snowshoe 2xl's in the winter for s'plorin....
