How about changing the colour balance or/and hue/saturation of the stock texture. It will look something like the screen I've attached.

I have to deal with the width of the room/wall segments and usually the door should be thinner than those, but there are special doors included in the pack as well.

I'll think about that

I have a similar door so I will just change the colour and will attach a screen in the next post.
Of course after the pack's been released I will take requests for resizing the doors (if technically possible), changing colours etc.

I don't have any other choice
Thanks for the ideas!
Edit: attaching screen...
