You probably have realised this, but take heed that these settings severely cripple the font. All OpenType layout features are dropped, including kerning (!), and hinting will be completely stripped. Also the name table is removed, which is probably against even open font licenses, and at the very least bad form. (It's like stripping the author name from open source JavaScript libraries)
It's a fun exercise in trying to get a small font file, but the sacrifice in legibility makes this very unsuitable for production, especially since you'll be talking about just a few kilobytes.
