I don't know how to use foobar to change the tags and metadata.
Interesting approach here may be/is to use something that will keep flac and mp3 trees in sync, like http://robinbowes.github.io/flac2mp3/ (say you just change some metadata on some flac files, it will only update those and only metadata)...
Now to figure out Perl.
I used LameDrop. I left everything on default except I made only one change to the encoder options. That was to use the VBR slider bar and slide it all the way to the right for the max and the max is 256kbps.

If you can figure out a way to make it work for AAC I'll thank you kindly and ask you to share the result with us mere mortals.
I guess VBR 256kbps is not what I want?
-V0 (approx 256kbps) multiply FLAC GB by 0.31-V2 (approx 200kbps) multiply FLAC GB by 0.24-V3 (approx 180kbps) multiply FLAC GB by 0.22-V5 (approx 130kbps) multiply FLAC GB by 0.16
