It's difficult to get it right since it's hardcoded with the UI code. You have to edit it yourself just for that.
Also, minimap EUI code already has the capability of resizing, it's just there's an Antiquity Sites UI mod that VP uses that overrides it.
I have to manually disable the UI mod just for this. I think I can combine the EUI version with the UI mod.
If you really want to do this, then you have to make a sacrifice to disable the UI mod by renaming the file or deleting it.
The location is here:

Rename the MinimapPanel files and the OverlayAntiquities_MiniMapOverlayHook file, so then it won't be loaded by the game.
Then go to this file, and edit the "Size" section of the highlighted line to match the config file.

The religion map is wholly different than the minimap. It can't be just translated like that since the minimap is what the game does and the religion map is a Lua trickery.
