Can double sized text be smoothed?

[datacute]

Is it possible to change the double-sized text to be smoothed, like how @technoblogy smooths it in http://www.technoblogy.com/show?3AJ7
His code changes the column and page address range before doubling 8 bits to 16, smoothing it, and then writing 4 bytes.
My code halves 8 bits to 4 then doubles them, and write that twice, one page at a time.
In order to smooth the text, I can't start by working on only half the data, so it's not a simple adjustment, rather a re-write of how I draw double-sized text, with very little program space left.

An additional complication is that the NameBadge project uses double size fonts of more than 8 pixels high. The smoothing technique needs a lot more code to work with these.

Note the top of the 'a', 'c', and 'e' isn't smoothed:

This looks much nicer. Unfortunately important name badge functionality had to be removed to fit this in. I might add a function to the Tiny4kOLED library instead.
