I would love to, but I can't fit my camera housing into a carryon with enough room leftover for other things I need to carry and after having it damaged while packed in a soft sided rolling duffle, I won't do that again. So I now put the camera, housing, strobe, dive lights, external hard drive, etc. in a hard sided pelican case.
I am thinking this year I will leave the dive lights and batteries at home and pack more gear into the pelican case instead. We can rent dive lights if we do a night dive.

Expensive toys , well protected won't be the cheapest to ship. If that's your gig there is a price of admission.
