Yeah that's fine mate. Is there any way you can overboard the ply with a cement board to give a better surface to tile to?

If the floor boards are deflection free then yes, but you must make sure that it is deflection free as a cement board does not add any strength to the floor it is purely there as a suitable surface to tile to.
