Reduce mesh face in mesh plane

Hi all,

Just wondering if there’s a way to reduce mesh faces from a mesh plane?
Or it just have to be remade?

I’ve tried Quad Remesh but it seems quite heavy.

Here I simply make the new mesh planes. Seem better.

Try this: A command opposite to SubDivide would be great - #5 by DanielPiker
