I have modelled the complete assembly on CAD and I can tell you there is very little room.
The design of the platter DD assembly is such that the platter sort of wraps itself around the motor assembly and the PCB. Hence the inverted dish shape of the platter which of course is a large part of the problem.
There is also a thick layer of rubber bonded to the underside of the platter which would not be practical to remove. There are other platters such as the SL1500 which do not have any rubber bonding, and which could be contenders for your suggestion. However they will not work on the SL1200 as the magnet rotor assembly differs substantially.
So we must resign ourselves to either putting something on top to improve the dynamics/sonics or look at an alternative platter design. Which in itself was not an easy task as the low profile of the motor assembly limits the options.
