Yes I was thinking about a takke-down TuffPak.

Also whe using a normal gun case I remove the padding from inside and instead place the firearm in a softcase inside instead.

I found the Boyt's site and the takedown softcases there are nice. I may get one.

But there is no way I can take a full length bag AND takedown bags so I might try "NE450No2" idea first ie using a full length softcase and folding it over. I do not have the luxury of a USA based resident's luggage allowance and will be taking kgs of camera gear as well.
