What are the practical differences between AC and DC transmission?
With LONG leads between the transformer and the rectifier, lots of EMI will be generated and radiated, as the diodes in the rectifier turn on quickly (microseconds, if not faster) and the rapid change in current thru the long-wires provides external magnetic fields that are very difficult to shield with just copper foil.

And place small capacitors (100uF) right by the rectifier.

Something like this
