But it might not be true for NN. Does anyone happen to know if KRNNKR and KQNNKQ are still drawish, i.e. if the threat of trading R or Q is a sufficiently powerful defense plan to secure a draw? And how is it with KBNNKB?

I don't know, but you could try a 6-man tablebase (I've used http://www.k4it.de/index.php?topic=egtb&lang=en to browse tablebases, though I wouldn't check this by hand).

I've been thinking about endgame (and piece-value evaluation) in Sjaak as well, and it's not clear to me how to do it except by manual input (which I don't want to do). So far I've come up with different piece properties to look at, colour bound being an obvious one. Another one is the ability to perform a tempo-move, which I suspect is needed to be able to mate a lone king (hence why you can't with two knights), but I don't know how valid such generatlisations are (I'd need a tablebase to test). I haven't really pushed that further though.
Maybe monte-carlo analysis could help here too (maybe that's too slow)?
