To the OP; Can it be done? Yes,, as others have pointed out.
As to why.
In many places,,, 40 S&W ammo is easier & cheaper to find.
Also,,, many forget that 40 S&W is used a lot in competition handguns. Brass is easily found, and cheap for reloading.
As for moon clips,,, I use a moon clipped 40 S&W handgun in USPSA competition. It was designed for them, and I've never had misfires due to soft primer hits etc. Of course,, I inspect my clips for any bends or out of shape ones. I have occasionally found one slightly bent, (due to being dropped rapidly due to being dropped during a course of fire) which I have flattened back out & re-used. Moon clips have their place in many handguns,,, and especially in handguns used for speed competitions, such as USPSA.
And with cheap & easy to find brass,,, using a 40 cal in a gun marked 10mm can be an economical way to enjoy it. But as noted,, clean the chambers carefully & double check to make sure you can chamber 10mm when desired.
