[DBZ] Could all the Namekians fuse together into one? And if do how strong would that single Namekian become?

Could all the Namekians fuse together in the way Nail and Piccolo fused together? If so how strong would that single Namekian become?

Theoretically, yes. And from the looks of things, it's a geometric growth.

When Nail merged with Piccolo, neither of them was strong enough to fight Frieza's first form. Piccolo's power level was unknown, but I'd estimate him around Vegeta's power level at the time. Nail was hovering at 42k. After merging with Nail, Piccolo shot up to well over one million.

After that, he goes from hovering near Goku and Vegeta's base forms at the beginning of the Android Saga, to fusing with Kami and being superior to Vegeta's Super Saiyan state, able to go toe-to-toe with Android 17 on a near equal level. Kami was weaker than the heroes were at the beginning of the Saiyan Saga, but merging with him still boosted Piccolo's power by at least fifty times.

A Namekian who had absorbed his entire species? He'd probably be able to throw down with anyone short of Beerus. And even then, the God of Destruction might be in his reach.
