Would a third option work?
 
In the Description section of the Macintosh Roman section of a TrueType font, include a line of text in a plain text format of which the following line of text is an example.
 
PUA.RTL="$E000-$E1FF,$E440-$E447,$E541,$E549,$E57C,$EA00-$EA0F,$EC07";
 
One could specify precisely which Private Use Area characters were to become RTL when using that particular font.
 
One would need rendering software that looked for such a string of text in the font file, yet, as far as I am aware, no approval from any committee in order to put this solution into practical use.
