> If they choose to return on Crew-9, the associated IVA suits do exist and would be sent up

This is SpaceX’s pitch. NASA hasn’t accepted it yet. The novel risks could favour using the Starliner suits in Dragon or no suit at all.

There's no benefit to using Starliner suits in Dragon since they can't be plugged in, and there is no risk to using Dragon IVA suits that are based on the measurements they already have of both of them.

Of course there is. They already have them and we know they fit.

We also know, by the way, the measurements of the Starliner and Dragon ports. Making an adapter is theoretically easier than making a new suit. If you don’t think so, then map every argument for that scepticism to remotely tailoring a spacesuit.

Measurements can change or be faulty or be critical at different parts of the body for different suit designs. “No risk” doesn’t exist in aerospace.

They should send up the new suits and then evaluate.
