So can you combine Raging Mongoose with Diamond Nightmare Blade and get 6 attacks with it at x4 damage for each attack that hits, for a TWF?

No. The rumor that Dancing and Raging Mongoose can be used without a full attack (which I helped prolong ) is negated by the following line from the SRD:

Full Attack

If you get more than one attack per round because your base attack bonus is high enough, because you fight with two weapons or a double weapon or for some special reason you must use a full-round action to get your additional attacks.

But even if that weren't the case, combining Raging Mongoose with a standard action strike wouldn't let you use the strike multiple times. It would just let you use the strike once, then make additional attacks that don't benefit from the strike's special text. (This is how Snap Kick works. Unlike the Mongoose boosts, it's an explicit exception to the rule I quoted above.)
