Nice work, great idea, I kind of agree to keep it simple as stated above,
But if you did want to make a blended join you could make a custom plugg.
Start by making a plug for each of the id of the 2 pipes you want to join, then cut and join the two internal plugs at the angle you want them to join at and weld them together.
Now you can slide the 2 pipes together on to the fabricated double ended angled custom adapter plug and secure with through bolts.
It would be a bit of messing around but, it looks great in my head, not sure if the idea in my head has come across into words though.
Like I said it would be a bit of messing around and I probably wouldn't bother to be honest.
Apologies if you just read this scratched your head and said to yourself, there a minute of your life you wont get back.
