Yes it would. There's just enough space in a T47 BB shell with an external bearing BB to squeeze a hydraulic brake line around the BB shell, depending on which make of BB you use. It's tight, but it's just possible.
If they were using a lugged BB shell I could understand it as there are no lugged T47 shells. But for a full fillet-brazed BB shell it's a bit of an odd one.
Brommers-
it's a custom bike. The owner probably requested it.
Still, with the CK sleeve for 30mm spindles, hydraulic lines won't fit in there.

So the only option for completely internal routing in the BB shell with enough room would actually be a custom machined shell? But would also depend on where the chainstay is attached to the shell to not interfere with the bearing threads.
Slow day here at work, might draw it out on CAD.

But why use such a small ID shell if you plan to run a 30mm spindle when building a custom frame? Wouldn't a T47 shell be a better option?
