Hi Brendan,
I was thinking of similar T or L ends for the CF trusses.

was this what you were referring to?
atm rc build page here

will check pics of your secondary spider vanes.
did you mean fix the cell onto a solid plate and fix the plate to the rear assembly similar to the AG rear ends?
Am drawing up a few approaches in cad. we'll see how it goes.
edit: if aluminium is used for lateral sections, would expansion have much of an effect as its lateral, not axial.
Doomsayer's Vixen rebuild is with milled Al plates.
have you seen the need for resonant frequency calculations at all for OTA's though its more for mounts?
that would influence settling down periods.
