without strain on the COBs and without considerable efficiency or lifespan loss? can you promise me that?
because if this would be the case, it would be way better to manage, much easier to build etc.

It is all relative. Some are fine with a Tc of 75C. I aim for 55C-60C with my recommendations. Even lower with air movement.
140mmx80 can handle the 80 watt well. The Heatsinks are tapped for 54mm and BJB needs 55mm. Not a perfect fit but it works.
Getting some 120mm for CLU058 and i think even they can handle 80W but may get a little hot if there is not enough air movement.
New design SST X heatsink can handle 120 watts. 5 weeks out.

Do you have a price for them yet (approximation is good enough) - for 16 pieces (maybe 32 if they are not too expensive, as i want to build two lights with 16 each). and can i place a preorder?

I will take 4 of them and 4 of the 72v cree 3500k and i will build a 4 x 100 to 120w fixture to test.should be good with 2 x mw 185-1400 right?

Still looking for a forum with the editing options I need, but I am getting there...
Meanwhile, a preliminary shopping list and some schematics.
My build:
Here you can see more or less all parts on top of each other. Not all is set in stone yet. I am not sure on the supplemental LEDs, or whether I include some UVB T5s. I will be using CLU058 117W COBs (I wasn't able to find a driver that could run more than one of the 182W Class, which need 103V). I am still looking for something that can run more than two COBs but meanwhile, I will aim for the HLG-320H-C3500 driver, it has a maximum open circuit voltage of 95V, and the COBs will be run at 52V, which works fine with the holders too, that can run a max of 110V. The COBs run with a forward amperage of 1,620mA and can take a maximum of 4140mA; the driver has 3,500ma available.
Not sure if the math works out, watched most of @Growmau5 videos and tried to figure it out from there. @robincnn also had a couple of helpful pointers and will probably be the source of several of the things I will be using for this build.
On the bottom, are the grow channels:
These are 300mm PVC tubes with 200mm diameter. The green dots are temperature/humidity sensors (one measuring inside, the other outside of the chamber), the yellow dots are par sensors (not sure if i will do this, but it's a nice addition to the data), the blue dots are 360° internal sprays, the light blue are 180° (the chambers are fed with fog, but the sprayers are for additional feeding, flushing and automated cleaning). The pot holes are a bit displaced to give the plants an equal and maximum amount of root space - there are grills inside the chambers separating them physically, while allowing air and water flow, to prevent as much overgrow as possible.
This is the Frame, which I will be making from aluminum extrusions; the heatsinks are also positioned here:
Last but not least a rough cut of cover plates. I will try to redesign some of @Growmau5 CAD files to make it fit the CUL58 COBs and the 120mm heat sink etc:
Questions, feedback, thought, tips and ideas are welcome as always.

I have moved the grow journal to a smaller forum - same software, better community interaction from the admins, very open to suggestions, way less commercially orientated. it is small and does not have the same amount of experts one would find here, so i will be frequenting these forums too. and i will keep you up to date with the biggest changes. and maybe, at the end of each topic, i will just post a detailed summary. But if you want to follow the project as it evolves, click the image in my signature. Love to have you with me over there!
