I double high number or letter will look like a standard letter that will just be narrower unless you are displaying text in a narrow font. In that case it will look like a separate character...
This will be very confusing. Besides I don't like mixing bases and more than using octal for represents 8 bit bytes. It was confusing to use base 4, base 8, base 8, base 4, base 8, base 8 etc.
How will you display the rest of the data. Will you use 65536 glyphs? That is a monster font. Better would be to use the top 4 bits of the low order 2 bytes then the bottom 4 bits of the same bytes.
In any case you are going to a lot of trouble to avoid vertical hex which is the simple solution. Remember "keep it stupid, simple".
