I am aware that the turtles are named after the artists.

If you'll note, even a cursory scan of the artist's wikipedia pages would indicate that Donatello is primarily remembered as a sculptor, and Raphael for his pencil and painted works.

My point is, save for being Renaissance artists, the two have nothing in common, except that they're both Italian, and both had Ninja Turtles named after them.
