Yes, you can when my kids and I go I use the .223 for my shooting and they use the .30 cal on the .204,.223,.22, the only thing is the POI's will vary due to the different weight as discussed on .204 actually they increase the FPS to appx 15 fps more. I have hearing issues and I can not tell the sound db's from the .223 can vs .30 can but to me the .30 is more effective over the .223 but again thats me.

Yup, it works fine. The .30 can is more expensive, so there's a financial reason to stick with your needs at the time. But then again, if you later decide to get a .30 can, you get to go through the entire fun again.

The volume of the .30 is going to be larger, so in theory it will help quiet it a bit more. It's going to be larger and heavier though, so if you're thinking about weight being an issue there's a reason to go with the smaller one.

I decided to go with a .223 can instead of a .30, but I wonder if maybe that wasn't the wrong move. Another couple or three hundred bucks and I'd have had a much nicer .30 can that couple be used with a .300 BLK or .308 rifle.

technically as long as the hole in the can is big enough for the bullet to pass through, and the threads are the same, any can will work. Just remember more goes into the design of a suppressor than just baffles and some sound dampening material. Suppressors are designed for a particular sound wave, or harmonic, and will drop db better in that particular frequency or sound wave than any other.
if at first you dont succeed, get a bigger hammer!

I run my 30 caliber can on my M14s, 7.62x39 AKM and 5.56mm AR-100 and haven't run into any problems.

Yes; but the .30 can will also have a bigger hole than necessary for a .223 suppressor which will counteract the extra volume. A .30 suppressor on a .223 is almost always going to be louder than a dedicated .223 suppressor; but not dramatically so.
