I like the advancement, but perhaps we could figure out how to do it without referring to "number of zombies"? I also think the way the HD range is laid out in the 2nd table is slightly confusing because the "base" HD is below the "starting" HD of the size. I also don't want to call the individual bodies "zombies."
Well "zombies" is just a placeholder, we could just as easily call them "bodies", "wanderers" or "lost souls".
I quite liked using the total number of "wanderers" in the 2nd table, since it makes it easier to adjudicate merging lost souls.
It's fairly easy to fold the two tables together, though:
HD Advancement (by size)
. . Medium = 4HD and 2 wanderers, +1 HD per +1 wanderer
. .. Large = 8HD and 6 wanderers, +1 HD per +2 wanderers
. . . Huge = 17HD and 24 wanderers, +1 HD per +12 wanderers
Gargantuan = 32HD and 200 wanderers, +1 HD per +40 wanderers
. Colossal = 72HD and 1800 wanderers, +1 HD per +100 wanderers
To simplify a bit, could we make the merging process something that takes long enough it won't affect a battle immediately, so the DM doesn't need to track the corpses? Then we might be able to keep this framework but simplify somehow.
That's OK, I was thinking it was something that didn't take place in combat-time, especially with the larger lost souls that need to absorb scores of victims to grow.
There's nothing to stop us saying that merging corpses takes, say, 1 minute per wanderer, during which time the wanderer being absorbed can't attack but can be targeted and destroyed to forestall its absorption.
