I do basically the same as you, usually shooting photos but if there is something interesting i shoot video with my LX-100
There is definitively no substitute for strobes shooting photos, their power and color is simply the best.
For macro you may use strong video lights, but often you blind the critters and they disappear just a fraction of a second before you shoot.
There are different Keldanes, expensive stuff but very good engeneered lights and wide soft light spread, particularly for video but usable for near photography too.
I use one cheap Ano v70ws video light, 5000 lumen and rechargable without opening anything on the torch and it works fine.
I often have the video light with arm ball attached in my drysuit pocket and just the strobes on the housing,
if i need the video light i hold it in my hand or switch one strobe with the videolight.
As you have a rather bigger housing you may install the video lamp with a not too long arm to the hotshoe on the top of the housing.
Keep one thing in mind, for more than 1 ft away you need power, real power, at least 6000 lumen and 2 lamps are better than one.
