It's my understanding that all of that type of demon, even if they've taken up residence somewhere in runescape, at some point originated from the infernal plane - especially greaters and lessers.

As for bonding it with a human or elf - and this is obviously nothing but speculation because there's no lore anywhere near this idea - I would still think that the demonic half would rip itself to shreds rather than be bonded with a human. And possibly a proud elf would do the same for being bonded with something as barbaric as a lesser demon. I guess, in theory, a (mad) scientist could eventually get a combination of docile humanoid + demon that didn't instantly die or commit suicide or something like that. (Not that I would advise it anyway; wanting to play a "good" or "controlled" demon is a top candidate for becoming a Mary Sue, even when played by good roleplayers.)

We don't have an article on hybridisation because no one has written one yet. Although, the subject has been made pretty clear. Official Jagex statement was that all sentient races were genetically/physically capable of interbreeding naturally. All it really comes down to is the likelihood of such a union actually happening. For example, a Goblin-Elf baby is downright laughable, except perhaps in a rape situation where the goblin overpowered the elf as a form of abuse.
