NLA coolant hose

I've got a unicorn and then some. Replacing heater hoses on the 524td, and this coolant hose is NLA. Can't find it anywhere.
Options:
  • mock one up with a few junctions and hope it doesn't leak (no thanks)
  • have a silicone hose company fabricate a replacement (sent email)
  • look at a universal solution like gates unicoil (too many bends I think)
  • go to an auto parts store and hope I find something close
Any other options I've overlooked?

How about one of these things and some straight hose?

In theory you could reshape a hose if you could make a form, pressurize the form to 90 psi, and heat it at ~330F for ~20 minutes. Other than that being practically impossible on a home scale it's an option.

Since it's a heater core hose (I think) how about finding one from an M20 E28? There's a good chance that they are similar.

I checked the M20 diagrams, seems different. This is one of the hoses off the 4 way T.
I looked into the springy thing but there's 2 bends, different diameters at each end, and a little rise at one end.

My remaining options are: cut off a bit of the existing hose and clamp in a new spot, hoping it will reach. Or, ship this off to China somewhere, and have them make me one.
I don't think this can be 3D printed otherwise it would be a good candidate.
