...oh, yes, it'd be very different. Though the exact details would depend on how you merged the cosmologies.
The thing is, y'see, Sburb is far more important than it appears; it's intimately intertwined with the mechanisms by which universes, specifically including the universe in which it is being played, are created. That means that unless you're redefining what Sburb is and rejecting a lot of the Homestuck source material, you'd have to redefine the NGE universe in Homestuck terms.
In addition, you'd need to take into consideration the various factors which exist outside of any one universe - including the Noble Circle of Horrorterrors, the Green Sun, and potentially Lord English (though that gets kind of murky). Not all, or even any, of those would necessarily have to be involved - but it'd still be important that at least the author know why.
I'm not even going to begin to touch on the fourth- and fifth-wall-breaking aspects of it all, and the bits taking place in locations which are None Of The Above, such as the Yellow Yard. Those can probably be safely ignored for the purposes of such a crossover.
I could probably ramble on at length about things which would need to be taken into consideration and possible ways to do it, but I'm not sure that would be entirely appropriate. I'll just note that although the canon NGE plotline does involve the destruction of the world in some sense (Instrumentality and the oceans of LCL), Sburb leads to the destruction of the world in a rather more complete sense (planetwide showers of huge flaming meteors) - and that's just a side effect of something much bigger; the virtual glassing of the Earth isn't even really very important in the grand scheme of things.
Yes, you could do a crossover/fusion which doesn't deal with that - but I think that if you don't deal with that, you're not really doing the whole thing justice.
(Sorry for the somewhat extensive white text; I'd rather not risk spoiling things for anyone who hasn't read Homestuck yet.)
