Buy used winter garden awning - Does it make sense?

Hello everyone,
I am new here in the forum and recently bought a single-family house.
It includes a conservatory. Unfortunately, without an awning.
Now I would like to install a used awning... but unfortunately I don't know if it will fit.
Normally, I trust myself with everything, but this is a bit uncharted territory for me..
My conservatory is 6 m wide and 4 m deep,
The used awning is exactly the size I need., ONLY unfortunately my conservatory is slanted at the corners. see photos. so the outer supports would hang 2 m in the air.
Would that work or is that not possible at all?
P.S. The photo with the white house shows the used awning.

Regards Marcell

That is definitely doable. However, I don’t see how you want to mount that thing on your roof so that it will still be watertight afterward. Is the glass on the roof or plastic? Are the strips in between aluminum? I would consult a professional.

that is glass. in between are aluminum profiles. yes.. I had almost thought that,
