Ply first, then self level over with a suitable flexible self levelling compound.
The very best for this application is Mapei Fibreplan - fibre re-inforced, flexible, designed for plywood floors
Not sure about depth in one application for this product, may need two applications

would do same as 'leatherface', not used mapei sl before but like there gear. Got a flooring supply company round the corner which stock ball and co, never seen it anywhere else but good range of products and never had a problem.
