Speculation into what future versions of Dragon will involve

[CuddlyRocket]

I can see, if one needs custom per astronaut suits, that one would need new instances but I'm not clear on why new designs are needed. ... I'm just surprised that SpaceX would go to this expense.

Given SpaceX's mantra of reducing costs through reusability and modularity, I suspect that they would have at least looked into the possibility of designing space suits that can - to a greater or lesser extent - be reused by different people and have component parts swappable out in case of damage etc.

After all, these won't be EVA space suits; they'll be worn during ascent and descent where all they need to do is protect the wearer from depressurisation and flames.
