It's an interesting consideration but it doesn't work for me, personally. V'ger came from a world of sentient machines. These are fully 100% artificial life forms. The Borg are essentially cybernetic organisms, beings with both organic and biomechatronic body parts. I can't see the sentient machines introducing organics into their creations and all of the pitfalls that come with it. I think they would be for more likely to create more sentient machines like themselves.
Moreover, when V'ger merged an organic humanoid (I believe Lt. Ilia was Deltan) and the machine, the result was a flawlessly perfect looking woman - a far cry from the pasty faced techno-zombies that are the Borg. Sure, 7 of 9 was mega hot, but only after some serious reconstructive surgery by the holographic doctor.
