Because he wants to kill Spider-Man himself and not let anyone else to do that. And he is not totemistic being, so Morlun would not have as much effect on him as he has on Spidey.
The Venom team-up was already done. It was called Maximum Carnage. Yeah, they could do it again, but I'd hope the writers are more inventive than that. Maybe Spidey could call on his New Avenger friends. I bet Sentry would whup the pants off-a Morlun....hehe.
Nah, I think Parker finds a way to reverse the tables and absorb Morlun and in doing so gets a large power upgrade ("The Amazing Totem Being" anyone??).

P.S. If that actually happens, you heard the rumor here first!
I just read an off-shoot comic of "ASM" (still continuity though) where Peter was wondering about his spider-sense, and the vague feeling that he is connected to something greater through it. It's during a series of encounters with (supposedly) a Buddhist god seeking vengeance, that helps him bring down some criminals.
In any case, I have a theory that the spider-sense is much more profound than we realize. My first instinct is to guess it's a toned-down version of cosmic awareness, but that seems too easy (and also a bit outlandish at the same time). But if there's any upgrades, don't be surprised if it's connected to the spider-sense.
I'm thinking some sort of heightened empathic abilities and an understanding of what they are....just enough to let him stop more crimes, but also feel the pain of those around him. They like making Parker suffer.
How about recognising people with the spider sense.
If he fights someone often enough his spider sense could save the way it tingles and peter could recognize some eone like the Green Goblin on the way how his spider sense tingles-
Or some kind of telepathy defense. If anyone wants to read his mind his spider sense could go an rechannel the attempt throwing back to the telepath with a little pain to the user. So next time when PRof X wants to read his mind he gets some serious headaches.
hey you just hit something but what if spidey gets a similar power like morlun has that lets him find the same person he has come in contact with no matter where they are.then he use's this to find norman osborn and kill his ass.then parker finds his baby its about time something good happens for him.
