Thank you for trying to help, but the most valuable thing is time and this is undoubtedly a great waste of it, if compared to simply putting the elbows as they go apart from the fact that aesthetically it looks very bad and could not be accepted anywhere , and if we see those wrinkles and other imperfections they could affect the flow of fluids, not only that, but in case of an obstruction when two pieces are joined with heat, then all that remains is to break them to decouple them, I think that cheap is always expensive.
