Are you saying that the preferred approach for the brakes would be to use the continuous outer run lever to noodle (with outer zip-tied or clamped) rather than subject a clamped STOP to forces it might have trouble with?
Re the final para i had the impression that using, even in an adapted way, that metal squiggly pipe near the seat tube wouldn't work as it would curve the inner one way and then it would have to curve straight back to attach to the v arm. Its original purpose of course was to get the cable in the centre for the canti.
What I'm saying is that you should (with a new inner obviously) leave the cable run as it is, but trim the plastic bit flush with the 'tail' of the guide tube. Then fit a short length of outer and a V-pipe in the usual way, with a suitable ferrule between the guide tube and the cable housing. Cable housing is designed to be flexible (some more than others, and some can be preformed into curves if required), and if that isn't enough by itself then there are such things as flexi-noodles for the V brake; you could (say) simply use two of those if you wanted to. Like this, with or without a barrel adjuster, different lengths too.
I have little doubt that you will be able to make something that will work just fine, I've seen it done many times before.

Maybe in theory...however 5 years and 8000 miles on my MTB would suggest otherwise. It never moved.....
One swallow doth not a summer make; whether the thing will move depends on a lot of things, many of which are outside of your control.
A lot of gear fittings used to be 'band-on' and they were just a PITA even though they saw tiny cable loadings. If band-on brake fittings (without stoppers on the tubes) were a good idea you might see them fitted OEM on some bike frames (e.g. which are intended to be versatile). I don't ever remember seeing such a thing being fitted and I think the reason is that it just isn't reliable enough.
