It certainly is possible to use larger text on the 64 with relative ease.

Compute's Gazette once had a little program that let you use double-width text
on the 64. Not sure what issue, tho.

In case you want to write your own routine, it would go like this:

Duble width text:

Define the normal A letter as the right half of 'A' letter, and the REVERSED
A letter as the left half of the A.. So, when you would be using the new font,
to type a double-width A, you'd type  A+RVS[A]...

When you choose to use either double height or double width, you loose the
"reversed" text option. When you choose to use double height/double width, 
you have to give-up something else, such as maybe lower-case letters.

2x2 s the most you can do with a regular font. By using raster interrupt, you
can use larger fonts, but that gets tricky.
