How about borrowing a bit from LA Man and giving MA Man some scholar with a minor access to Astral and Earth? A mediocre researcher with a 25% chance for 1S and another 25% for 1E.
Or perhaps a 'learned monks' theme - give these monks same 25% chance to have 1E or 1S. Its not much, but even S1 is a big boost to a non-astral nation.
