Thats a fair assumption , though it should have less self weight deflection due to its lighter weight . The strength of the glass sandwich comes mainly from its thickness, and I assume these mirrors are at least 40 to 50mm thick , and structurally the fused mirrors should behave like a monolithic mass.
So my guess is it should be a little stiffer mechanically than a solid blank of the same aspect ratio. It's better to pull off a really good cell with less points than not get quite right a more complex one . The edge support on those mirrors with just front and back plates at the edge looks trickier . Maybe just a single cable sling between plates at the C of G ?
I would be interested to see the Fusion 360 results if you get any .
