When V-cube 7 was manufactured, I was always considering how to DIY it to 8*8*8. I once DIY a 6*6*6 using a 4*4*4 cube and that took me 3 months.
The theory is very simple -- The inner structure was a Rubik's 4*4*4 structure, add one layer into it and fix the orbit of the inner ball structure. However, it's REALLY hard to make it because every part was needed to be modified and the size had to be calculated very accurately. I failed at the first two times.
The first time is just an attempt, so I didn't took photos.
The second time: The inner orbit is not very round-sized. You can see as following:
This was the third attempt. I was satisfied of them.
I could not help trying them when only half of it was completed. I felt it was pretty good under the calculation by hand. So this struture should be OK if it was manufatured like this.
Generally speaking it was done, and will not easily get POP. But I'm stilling working it to make it more fluent.
The most difficult part is the fourth and fifth layer of the cube. The orbit has to be VERY round-sized. I fixed the orbit for 3 times. You can see as below, it was a bit different from the first picture on the top.
EDIT: The last two layers:
