Stacking rectifier boards?

Due to layout & space issues I may stack the rectifier PCB's for a pos/neg PSU in a preamplifier. This would put one bridge directly above the other on another "deck".

In order to avoid coupling, cross-talk, field interaction, etc. I was thinking a spare 20mm space between the TO-220 rectifiers and the board above, so, 40mm risers stacked on top of the lower board.

The rectifier output is +/-19VDC with a max load of around 200mA and the caps are screw terminal right next to the bridges.

Does this seem a good plan? Any downsides that could affect the quality performance of the result?
