Not only for macro but as you say for wide angle or semi wide angle.

 

Actually on my example with WA shots I swim with the camera in my hands.

But precisely, on this instrument, how could we add rolls to then put the tripod

 

Hummm you will probably have to make some modifications, or else:

 If the feet have a common thread (1/4“ or M8-M10 you might find compatible 1” balls. Another option: many sliders have a 1/4” photo attachment at the bottom to mount them on tripods. you could take advantage of it to attach a plate with 1" balls.

However, regarding the equipment used on professional productions, for sliders you don't use ball bearings but use Teflon friction bearings or similar materials. There is a company that sells all the parts, and in the catalog there are also parts designed to work underwater. They also supposedly have a technical consulting service to help make custom solutions. there are also lots of projects in the film and TV field on their page.
I leave links below for those who would like to learn more:

I purchased an INON UW Tripod System and a NiSi Macro Focusing Rail (see photo). The build quality of the NiSi Rail looks good.  I particularly appreciate the large diameter knob on the focusing rail and the 180-360 degree rotating head on the tripod.  I already own an Ultralight tripod plate, which I plan to use with this setup. I'll be testing these items in Anilao in April-May and will share my experiences sometime in May or June.

I happen to do these frontal tracking shots with a medium wide lens inside small soft coral forests

Could you give a link to your video to show the final result?

Sorry, I've nothing online at the moment. I have to dig into my archive.

ATM I found only this example of thin DOF inside a white gorgonians forest shot by my buddy for an upcoming feature.

Lumix 12-35mm @F2.8

Thank you for sharing.  My micro slider will not help with this:).
