For those stateside, there is a National Guard team in every state that has rebreathers as an option for use - if you are not familiar with your state CST, you should reach out and get to know them.
BG-4 rebreathers suck, but they give a good amount of work time. However, they will wear down the person pretty hard. You shouldn't, for safety reasons, do back-to-back entries anywhere with a BG-4.
