Seems a serious overcomplication. Tesla coils are very, very insensitive to
the primary resistance. In a coil processing up to 1000 W, maybe more, the
use of tubing, or something heavier than #12 wire is good only for the
appearance of the device. Any improvement due to less resistance would be
noticeable only with instruments.
Corona at the edges, only if the ground or the top terminal are very close
to the coil. The primary voltage is usually not high enough.
