From 1x12 back to 1x11 why? to have more usable cogs!

Dears, I have just acquired the new Cannondale Trail SL2,
it is equipped with a 1x12 , Shimano Deore M6100, 10-51, 12-speed
10-12-14-16-18-21-24-28-33-39-45-51
and a Shimano M6100, 30T. A great bike! I'm not a strong rider. It is my first 29er, I'm coming from a Surly Troll 26inch 2x10 speeds.


I have tested the Cannondale Trail SL2 during two weeks, I noticed I never used the cogs 10 and 12 .
So I have a 1x12 speed system but I really use 10 of the 12 speeds.


I'm thinking to move to a 11 speed cassette. Why ? to have more usable cogs!
Here is my idea :
I will take a Shimano Deore CS-M5100 Cassette 11-speed 11-51
11-13-15-18-21-24-28-33-39-45-51
and remove the 3 first cogs 11-13-15 and replace them by 14-15-16
from a Shimano Ultegra CS-R8000 Cassette 11-speed 14-28
it will give me a 1x11 with  11 usable cogs :
14-15      -16-18-21-24-28-33-39-45-51
(my derailleur will be a RD-M5100-SGS the 1x11)
before I had 1x12 with 10 usable cogs :
10-12-14-16-18-21-24-28-33-39-45-51

As you see I will still have the same cogs I used before (on the 1x12) and one new intermediate between 12 and 16, the 15.


What do you think about this strategy?

Kind regards,
stoz


(of course I will need to change the rear wheel (for a 11 speed hub), derailleur RD-M5100-SGS 1x11, the shifter and the crank to be 1x11)
