The bolt has to weigh a lot more for those other calibers in a direct blowback firearm. In 9mm the bolt weighs about 1.7lbs. For 45acp and 10mm the bolt would need to be 2.3 and 2.8lbs respectively. It can be done but would require a lot of work to change calibers.

It's more than just scaling the bolt. Heavier bolt means heavier recoil springs. Heavier recoil springs means larger/stronger receiver. Magwell and magazines also have to change for each caliber. Magazine design is one of the most difficult parts of creating a self-loading firearm. It's easy to make one that functions; it's hard to make one that functions reliably (even when using an existing design as a reference). You can "cheat" and rely on commercial mags, but even then you'll usually have to tune the feed geometry since the behavior of a .45ACP cartridge is going to be radically different than something like a 5.7.

There is a 9mm version of the Decker 380 in development right now and despite the cartridge itself being nearly identical just 2mm longer, nearly everything except the fire control system has had to change to some degree.

I wouldn't give people saying it won't work much weight in my decision of what you decide to pursue. It's takes considerably less effort to list off a few reasons (That doesn't mean they're not valid ) why you'll encounter difficulties with a given endeavor rather than providing suggestions because that requires original thinking.

Have said that I am capable of original thought
And I too have built a rebel 9! I would love one in .22lr .... I know that's probably the last pistol caliber cartridge you wanted to hear suggested .

The decker is a fully diy in .380acp and the 3dp90 is a a diy 5.7, so it for sure would work, the only thing in the 3dp90 that's usually not diy is the barrel, but they do include the blueprints in case you got a barrel blank and a lathe. I dunno about .45 since its such a bigger round, the bolt would have to be heavier and the upper stronger, but you can for sure do it
