There's really no difference in the risk that your 3B and C get injured in the same game as your C and backup C getting injured in the same game. And the result is the same, you go to the emergency catcher, probably lose that one game, and then call in replacements for the next game.
To me there's no difference in risk, why would it be scary? What you have with my idea is increased flexibility, you still have a backup C but he's also your starting 3B, so you don't need an extra roster spot just for a guy who plays 20% of the time. I'm trying to figure out what's wrong with this idea but I can't. Maybe players just don't like being both, when they are done catching they just want to focus on one new position every day?
I think there is a difference. In the first scenario, your backup catcher is playing third. In the second, your backup catcher is on the bench and only comes in if the starter gets hurt.
I don't think there's a huge risk either way, but there is a difference. Maybe not significant.
