Here is my take @Doc Harry. Going to a point and shoot is difficult to do when one is used to using a DSLR or Mirrorless Camera. Why? You loose lots of control that at the moment, you take for granted. In photography, we create images from things we see using the settings on our tool, the camera. If the tool is not there, we become compromised.
You can simplify what you have and see how you feel when you dive with the rig.
If you are not going to take UW photos any longer then you can sell the stuff on ebay or KEH. Last year I sold an Ikelite housing for my D300 to a guy in HongKong. It worked out well for both of us. Currently I shoot a D500 with Ikelite DL200 housing. Smaller and more lightweight.
Hope this helps.
