Absolutely. There could be several improvements in that way. Maybe along the lines of turning a square of 4 dots into a circle, a line of diagonal dots into a smooth line, etc. Some words can be drawn out pretty simply with a pen, as if the line were passing through the positions of where the dots would be. This is even more pie-in-the-sky than using it as a font but is fun to speculate about, though I fear it may ruin the afternoons of a few HN commenters to see it mentioned.
