I've seen this problem discussed multiple times. People want ‘handwritten’ fonts for one reason or another, but then once you notice identical letters you can't unsee them. The thing about ligatures is that they don't permit true randomness, but you can cycle through a set of glyphs for a letter—if I understand correctly, you don't even need neighboring letters for that. However, people stop after adding just a few variations, and that still looks mechanical because the same letters occur many times in a paragraph. For good results, you should just keep throwing more variations in—like a couple dozens I think (maybe depending on the frequency of a letter, but then if you come upon ‘QQQQQQQ Inc.’, the effect will be ruined). Also, invariably people tune kenning in ‘handwritten’ fonts. Why? Pretty sure they don't do that with actual writing, do they? If anything, I'd add some subtle sloppiness to the font generator's output.
