I am considering adding a Tech-Sight aperture sight to my 10/22. I think that would improve the accuracy. And, it would make it closer to the sights on my Mini-14. I do think that it would be an improvement over the factory "open" sight. This replacement sight will cost $59. I do not think that is unreasonable.
Inasmuch as 223/5.56 ammo is getting hard to get, it will be more difficult to practice with my Mini. I think that modifying my 10/22 this way will make practicing better. And, I will be building muscle memory for both guns at the same time. Sounds like a win-win situation to me!
