Basic question but regarding multiple cylinders diving.
Have you switched regs between tanks underwater?
Planning: What circumstances would have you decide that was the best course of action towards safely returning to the surface?
Dive execution: What potential risk factors do you see?
Post dive: In salt water are we fairly certain the SPGs would be salvageable? A good soak for the first stage itself, or is a rebuilt the minimum after forcing a few cc of salt water through it?
I've had 4 dives with decompression obligations where I considered switching out a regulator to gain access to the unused gas: 1. Blown hp hose oring. 2. An instructors deco bottle DIN oring blew. 3. A drowned deco rebreather I had hard plumbed to an o2 bottle had me left with extended air deco. 4. A badly torn mouthpiece and a metal reg made breathing wet or uncomfortable. (Not a golden retriever nor possessing other birding breed genes).
Each time contingency gas reserves were sufficient to sustain the total gas loss without incident. However, it would have been nice to once again regain a redundancy in case of further failures and also add extra conservative with an extended safety stop.
This was pondered with a 45 minute air deco obligation while my instructor had a full o2 bottle rendered inaccessible by 20 cents of vitron. (He rejected the offer to buddy breath or share my o2 as conditions were conducive for extending the dive. I stuck with him on o2 for solidarity)
Well, that's that.

P.s. I am confident some of you have had X number of divers over Y years and due to Z training or L brand or Q maintenance schedule or P deity have never experienced a situation where this might be even a consideration. For you, I am glad and happy you've not had dive plans modified due to such issues.
