[Fullmetal Alchemist/Brotherhood] Could immortality actually be achieved through the philosopher stone and not just extreme longevity ? Like could u have an alchemist turn you and a few other people into a small philosopher stone when you're near death and then just create bodies for u later.

Then just separate each soul into a new younger body and  repeat ?

You and a *few* other people?  No, absolutely not.

The philosopher's stone doesn't really create *limitless* power, it's more like a super battery that relies on harvesting so many human lives that you wouldn't feasibly use up all the fuel.  You'd deplete the battery on trying to transfer distinct souls alone, never mind constructing new living bodies for them to inhabit. 

There are also issues of whether soul/identity is truly transferred or whether the alchemist is simply constructing their interpretation of that person.
