Apart from being a can of worms, wouldn't it also be pointless ?
Every CBT will have to be corrected for relativistic height anyway
so wouldn't the tuning just turn into yet a C-field and not add
any actual improvement ?
If I have understood it right, the main thing about the RF part of
the cavity is stability and symmetry, more than precise dimensions ?

Never attribute to malice what can adequately be explained by incompetence.
