My neighbor is a guy that would be sure he meets applicable codes. The
Fridley electrical inspector is a good guy, very willing to answer
questions and help homeowners do things right the first time.

The three-elbows problem was mostly an interesting puzzle for me. If
an electrical shop can bend the conduit, that's the clear way to go.


A small, residential only, might have a bit of a problem. (That was
the focus of my business back 'in the day'. I did make a few 'offset'
bends with a small hydraulic bender so it is doable)

But bends like this are done all the time in the commercial electrical
world. If you made up a sketch with the planes on which the conduit
will 'lay' and the various offset dimensions, a commercial shop should
be able to give you a bid.

Sounds like it might be a fun Alibre project using the NEC
requirements for bend radius grin.
