Problems with isometric transparent walls

Hi. I have an isometric tilemap with z as y and made the following map:

The problem I have is that behind those walls a fight would be going on, therefore I have to make these walls transparent, but when I do so, the following happens:

What I would prefer is for the lines that form from the overlapping tiles to disappear, forming something that would look more like a window. How can I solve this?

If its 2d art then just make a transparent version with no outline and change the sprites to the transparent version when you want it to be see through

Different approach: Age of Empires solves this problem by using a character outline. People fighting behind the wall are visible by their outline.
