Color Control component with internal node input?

I have made this thread Some way to fit or stretch a FF result automatically into a square


In the Color Control Image placement you can convert any external source image to square using the FIT or STRETCH or FILL option

Color control does not have any node connection, so you can not connect any component to the color control to be able to fit, stretch or fill with that result a square

So I wonder if there could be a upgraded or new color control component that can have a node input where you can connect internal FF components results to this color control, so instead of only being able to use external images, it could also be able to use internal images result made inside FF
