So far your looking very good!

Yes, and yes. The problem here is that there is a big jump
between a four inch coil and a six. I would reco two different
primaries for best performance, but you can trade off and make
one primary serve on two coils.

There will be some effect from any conductive structure that is
too close to the primary/secondary field flux.

You can do this on a small coil, but at higher powers I could see
where a problem or two might develop.
