With 40º of arc the Wavefrontier T90/Visiosat big bisat in the ends of the arc only render like a bad antenna of 55cm.
With + 50º of arc the Wavefrontier T90/Visiosat big bisat in the ends of the arc only yield like a bad antenna of 45cm.
Better with 2 antennas.

On OP's traditional 90 no chance.
Easiest to go with two dish solution. No need for 2x90, 1W (for Canal Digital) kan be done easily on ~60 cm dish. This also what CD gives you when you sign up as regular new customer. But it can be comfortably received on a well aligned 40 cm dish, but with less rain margin. So eg if size on a balcony matters, you could add smaller dish. Even a flat one if there are restrictions on the number of dishes.
But if you really wanted to it on a single dish, it can be done.
The now-long-out-of-production SMW OA-1600 has a physical span of 52 degrees. It performs more or less like a 1m dish across the span.
And since you can angle the lnbs for easy-to-receive sats quite a lot, I am certain 52.5e and 1w can be done.
But it is a big awkward dish, and is more difficult to set up than two single dishes. On the plus side, you can probably find a used one locally, as they were made in Sweden, and still pop up occasionally on blocket and the like.
