how would you fix this floor

went to look at floor that this guy had already hardiebackered and he wanted me to give him an estimate on the tiling it. He had several issues that I told him I thought should be fixed before it would be ready for tile. His subfloor was only 1/2 inch plywood with 2x8's 14 inches on center with a 12' 4" span. He also put the 1/2 inch hardiebacker with screws only no thinset. I told him this would "probably" most definitely have problems down the road.
My question is am I correct about potential problems and if he removed the hardibacker would putting down another 7/16" plywood be enough to solve the problem. I would then put 1/4" hardiebacker with thinset and nails (1/4" to help with height problems) as my CBU

he does have a deflection of L / 533 now if I did it right

but I would make Hardi down and go from there.

good thing is he can un screw it to take up the Hardi

L/310 is a little on the light side. The extra plywood won't cure that.
