Transformer Flux leakage and Vibrations migrating from the upper component to the lower component are probably your two worst enemies
Depending on the type of transformers used in the components will determine how much and how critical the Flux field will be
EI type (square box type) tyrannies tend to leak in all directions were as Torrid's (round donut style) tend to leak in a much more limited / narrower range
You can try shielding the transformer itself or use a platform with some type of shielding between the components
Note that in both cases you are dealing with lower level EM leakage ( vs higher level RF type noise ) and will require some type of permeable shielding like copper to absorb and dissipate the EM Flux field
As far as vibration control you wouldn't want to direct couple the upper component to the lower component as this would allow vibration from the upper component to migrate to the lower component ... possibly compounding the problem
You want to Isolate or decouple the upper component from the lower component so vibes are blocked from entering the lower component
When decoupling you must properly load the decoupling device according to the component to be isolated weight for it to work effectively
All decoupling devices have a resonate frequency point ... above this point the decoupling device will work properly ... below the res/freq/point of the decoupling device ... it can't handle the magnitude of the vibration and over loads locking up and will actually work the opposite and couple the component instead of decoupling it ...
