Voron 2.4 with 800mm print height

On a V2 I don't see why not. Just longer extrusions, Z belts, and wire harness to the gantry.

The only problem I can see is with more stretch in belts and more flex in the frame. Maybe you should consider to reinforce the frame corners more in order to not have too much of this effect. Voron frame is only 2020 and when the print is at 800mm high, al the moving weight is at the top. This will be the most non-ideal situation for the Voron.
But theoretically it will work for sure.

For vertical flex issues, you could look at something like this: https://github.com/FrankenVoron/DoomCube-2
I suspect that rigidly bolted side panels (not just edge mounted with the stock clips) would go a long way toward making it stable.
(Much like how the wood sheathing on a house frame adds significant shear strength to the walls.)
A cross brace or two on the front side would be an inconvenience for part removal, but might be worth it to help keep the frame front extrusions from bowing.
Come to think of it, I wonder if with 800mm extrusions, you might have issues with them being not straight enough along that length from the factory?
Another complication would be if this was to be enclosed. At that height, maintaining a consistent chamber temperature would require some extra effort.

solid screwed on panels fixed to the outside of the extruded members will do a mighty lot to stability indeed. But I would still put some corner strut in I think. If you buy a good brand, not nameless Chinese, they will be good enough and within stated tolerances. But stay away from those offered to you for cents per linear meter without any mention of who made them.
Lastly I do not think stability of temperature is a real issue even for something 800 high. The temperature might be higher in the top then the bottom but with a good heat soak, as long as the panels are closed well enough, it should be stable enough for ABS, ASA, PETG and nylons. I don't think he will have issues with that.
Hey! Yes, building a Voron 2.4 R2 with a print height of 100 cm is possible, but it requires some modifications.You’ll need to adjust the frame and ensure that all components like rails and motors are suitable for the increased height.Also,keep in mind the stability of the structure—taller prints can introduce additional vibrations, so consider adding extra support to the frame. If you have questions about specific parts or settings, let me know! 
I am trying sometime similar. I used 4040 for the frame and Hgr20 vertical rails as the mgn9 rails were difficult to source in 1m length. I am trying to build it with plastic pieces first and will CNC some parts once it comes together and moves ok. Using 4040 meant a lot of little changes need to occur and I don't trust they will all work out. The z idlers are different the nema 17 in the base wont line up etc ... If it works I'll post the f3d or step files. The goal is bigger all around 550mm bed. Still much taller than wide so proportions are off. The main issue I see is that feeding the filament seems a real issue with that much vertical movement if anyone has an idea I would love to hear it.
I have thought about running through the cable drag chain though all I see online is don't, it seems like it could work fine if the bend radius is wider. I thought about trying to attach the spool to the gantry but it would add a huge amount of weight and be uneven at that. I thought about trying to use another rail with spool on it that moved under gravity down as gantry rose and then when gantry lowered was raised. That would add mass to gantry, but also effectively lower the weight instead of raising it. So z acceleration would be negatively affected but the motors should not need to lift more weight.
