Fixed roof from HPL plate on a cat, possible or anyone done that.

[CaptainRivet]

Hi all,
Want to put a fix roof instead soft top on my FP Lavezzi cat.
Did anyone use or know of someone who done the roof with HPL plate.

The roof of Lavezzi is 420cm wide and length is 180cm till 230cm depending how front or rear I go.
10mm HPL is available as 4250mm x 1850mm means I could make the whole roof from one panel and then add 2nd plate to extend to stern by 50cm.
Like this could angle it 10-15 degrees downwards on the length part and over the whole width get a little curvature by letting the plate bend a bit.
Underneath stainless structure made from stainless 32mm tubes so I can actually use reling parts to stick it together (Jb weld instead grub screw) and avoid welding. in the center part a bit stronger to walk on over 250cm.
The existing one is 25 and 28mm tubes roof an downward facing tubes and 2 center support one with 32mm at the rear end where you have a center section you can walk over, which I could reuse.
Thoughts? Can HPL be used?
