That would be a very Heavy Card to support with only one slot screw holding in in the case you would need some kind of support for it.

You think? I don't see why. 

If you had an HC Water Block then you would know, they are very heavy plus add a back plate and even heaver.
I have 14 HC Water Blocks as long as they are in a Vertical Position it not an issue but it is when they are in a Horizontal Position.
Looking at using the below support for my current rigs that are in the Horizontal Position.

Heavy? Yes. However, with the backplate and waterblock, the cards are very stiff so the cards themselves don't really sag that much, at least I haven't found any sagging in any of my watercooled systems in the past. 
 

It is the PCIe Slot that you need to think about, the weight pressure on the Slot that is.

What is nice is when you have 3 or 4 cards with a good SLI (Water Block) it helps but no one makes one that will work with the HC.
I am hoping that EVGA comes out with one this year.

Tell me about it...
 
I used to pull all three cards out at the same time and just leave it in this configuration when I needed to get the cards out. When you have both the SLI terminal and 3 way SLI bridge on there, it was as solid as a rock.

I wish they'd make an AIO as thin as custom blocks are, the thinner the better in my opinion.

You have to remember the HC move Water only and the Hybrid moves Air and Water.

Going with liquid cooled VGA is much more practical from sagging point of view. Air cooled cards are just big chunks of radiator with some PCB attached on one side. Freaking enormous. 
 
Liquid cooled cards are much easier to handle. Weight of the card is usually concentrated near the core. A lot of manufacturers create only cooper-nickel base for parts where it matters leaving acrylic to cover everything else. This makes card very light at the edges and thus much less prone to sagging. Going with any form of rigid tubing largely/totally eliminates the problem by acting as additional support. Of course the easiest setup is 90 degree (Silverstone or now Thermaltake in e.g. Tower 900) - you can basically hang a car. :) Reverse ATX is also excellent as card(s) is(are) kept level from below. 
 
Running few liquid cooled rigs and I have no issues with sagging VGAs whatsoever, be it enormous GTX690 or GTX970. On the other hand 1080 which I received couple days ago just in testing sags like mad. I've got so used to cooling with liquid that I'm totally freaked out by these ginormous air cooled cards (like MSI GTX580 TF3 I have, Behemoth with B!). I can't guarantee that problems won't arise when using new Glacier FTW waterblocks from Phanteks. These are net 1.6kg for the block alone! Nuts. That's extremely heavy. I don't know about HC weight - and Swiftech doesn't exist in Europe in any form. I'm against blocks which aren't transparent acrylic over all important things, but my GTX690 Heatkiller block according to specs is only 1.2kg spread across two enormous GPU cores. I don't know what for Phanteks going so extreme, as at some point adding more thickness to the cooling plate becomes irrelevant and total waste of time/money while increasing stress on the PCB. One fault of Phanteks Glacier I discovered is that block is directional which means it doesn't have universal inlet/outlet apertures - that's insta-Fail in my book.
 
For 1080Ti I expect single slot bracket (family not only Hydro-Copper) and if not available I will certainly cut mine.
