There seems no reason why VDSL2 & g.fast FttRN shouldn't use the same physical boxes. Aside from the technical detail of the modulation, encoding and so on, the installation requirements are surely identical with comparable power consumption. It would make for an easy retro-fit too.
nb. I should add that if you look inside VM boxes (or at least the ones round here), they contain a similar sort of sealed, finned, weather sealed box with connections for fibre & coax. I also saw inside the adjacent power cabinet (vandals had prised the doors open - not difficult, they are flimsy). The power cabinet was atrocious. It has a 48V switch-mode power supply, rather like one a bigger version of what you find in a PC. Open vents with standard cooling fans and no attempt at sealing. The mains part had a meter plus, a breaker board and a plastic 13 amp socket as you'd find at your local Wickes branch. All screwed to a bit of backboard that was lodged in place. That clearly supplied he 48V required for the network cabinets in the vicinity via dedicated DC cables.
I have a photo somewhere, I'll have to dig it out. The box was unmonitored and VM ignored my message via their fault reporting page. I wrapped duct tape round the box and about 4 months later they put the door back on properly.

I found a couple of photos of the local VM equivalent. The network cabinet door was half open, hence the angle of the photo. Note how similar the die cast network box is to the FttRN one. Compare it to the power cabinet. I did it a slight disservice as the power supply is a UPS too and it's 60V, not 48V. Also the sockets are metal clad and not plastic and there's no meter. However, it's not exactly neat (and there's no monitoring of the enclosure).
I don't think the leaves and beer cans are standard VM kit.
Of course the interesting thing is how converged the network node physical infrastructure becomes when cable is compared with FttRN. Similar frequency of cabinets (VM ones seem to be about 100-200m apart and local power distribution). Perhaps not surprising for any hybrid architecture. Whilst co-ax is a better transmission medium than twisted pair, the cable segments are shared and the total length with all the spurs must be quite long.
