Even if it could be great, you can't get both results.
You can split your Aperture library into smaller ones by consolidating and reprocessing masters.
or
You can export your photos with the desired format (File > Export > Name format > Edit) and then do some shell/Automator scripting.
Maybe you can do both but, doing so, you have to save a copy of every photo you add each time exporting them as described above. Please note that this will (almost) double in size your photo library.
