This is awesome! I'm kicking myself for not proposing it :)
Unfortunately, your proposal defines a way to make multipath donations,
not multipath payments :(
In other words, you've lost proof of payment, which IMHO is critical.
Fortunately, this can be fairly trivially fixed when we go to scriptless
scripts or other equivalent decorrelation mechanism, when I think this
mechanism becomes extremely powerful.

This is a stretch. I'd stick with the increased reliability/privacy
arguments which are overwhelmingly compelling IMHO.
If I have any important feedback on deeper reading (and after a sccond
coffee), I'll send a separate email.
Thanks!
Rusty.
