I had considered this but actually rendering an existing vector font nicely is extremely difficult - on desktop a lot of work goes into it and the vector font takes up a lot of space. Originally we used a font created from a truetype font and it was a complete mess, which is why @NebbishHacker ended up designing something from scratch that actually rendered really well.
What might be a possibility is to render vector line fonts, but I don't think that'll really help you much there isn't a huge selection of those.
