I do believe that the Israelis did something akin to that as well.
The Israelis used the same gun but adapted to the original Sherman turret. The reason why is because they weren't very impressed with the original turret (they wanted something with better armor protection, and the original Sherman turret despite its modern reputation did that). Many of these were sold to the Chileans.
They also used a
105mm French rifle (very frequently misattributed to being the L7) adapted to the original Sherman turret.
Also, 99problems, I don't know why you don't think your drawings are good. They look fine to me.
