Combining Square Tileable Texture variants into one Material

The the below example I sort of have working, I can combining two textures, but my goal is to combine 3 or 4 textures into the grid. Also I’m recieving massive texture streaming warnings after doing it this way.

The two texture variants:


The BP and mask I’m using, lerping.



The nodes to the left just keep is scaled properly when scaling my plane.

The Result:

Does anyone have a simpler way of achieving this in a proper efficient manner? Where I could potentially mix 3 or 4 textures?
