I don't know Hytrel, but these flexible materials are the only ones I know, that could help to be moisture proof. Waterproof is another requirement and they will not, because they are too hard, that's right.
I think it hardly depends on your model and what you want. Can you give an example what you want to do?

You could try some of the flexible materials, like TPU95A from UM or Ninaflex which is much more flexible.

Thank you! How do these compare to Hytrel, for which Ultimaker has just published a material profile?

I knew nothing about the Shore scale of hardness, but according to this synopsis: https://www.artmolds.com/shore-hardness
I am afraid that Shore 60D may still be too hard to work well in a waterproof joint.
