I grabbed my travelwing to see how the holes would line up. With 11" spacing between the holes, I would need to cut through the center strap stitchings where they attach to the wing itself... not sure if I would want to take that risk.
Is the 11" spacing a standard with all backplates... or do different plates have different spacings (i.e. designed for other wings, etc.)?
I guess I am beginning to picture why it might not be such a good idea. I would need some way of attaching the wing to the plate and also add an STA. I reason I think an STA would be needed is that the possible mounting points of putting a bolt through the travelwing are pretty thin. I would not trust the wing to hold the tank (i.e. Pioneer 27 style... I think).
Any STA I used would need to be fairly short as to fit within the 12" cavity formed by the "O" of the wing. Otherwise the STA would pinch the bladder against the plate.
Brainstorming here... but if I were to find a STA adapter that was at a max, 12" long, I could drill a hole through the STA and plate so that the spacing is smaller than 11". I could then bolt this through the center strap at a place where it would not compromise the stitching. This way, the STA supports the tank rather than the wing. The wing's flat fabric sections (not bladder), are sandwiched in between the plate and STA.
Oh, just to clarify... the style of STA I was thinking of can be found on

I guess I am starting to turn this a DIY thread...
