My Astro cameras work in 14 bit colour. When I save a file in XISF format, it selects 32 bit,as default. Would there be a disadvantage in saving it as 16 bit, instead.
Generally when processing data you will want to keep the files in 32-bit format in order to keep the full precision of the number. Later, when you have a final image (perhaps saving as a TIF) going to 16-bit is no problem. Likely the answer to your question is, it really wouldn't be a big deal to manage your files like this. However, it is not common practice and it is not something I have done- so you will be on your own in terms of consequences I cannot foretell .
