Is it possible to make light map to be asigned to vertexcolor?

Is it possible to make light map to be asigned to vertexcolor ?
hello
I have not questioned at UE4 ansewer hub before and I am not good English writer.
anyway
I have much opotunity to deal high resolution mesh when I make arch levels.
I think it’s better way to asign light map to vertex color than baking texture when I deal high resolution mesh.
Adjusting high resolution mesh’s UV is too troublesome.
Sorry for my poor English.
