Five Letter Girl Names

Fenix is a spelling variation of the place name and mythological name Phoenix, possibly inspired by the Romani form, Fennix, or the Spanish Fénix. Derived from Greek and meaning "dark red", the phoenix is an immortal bird that, having lived for a number of centuries, would be consumed by fire and rise from its own ashes.

Even in Sweden, Barbara is preferred. If you're looking for a variation to spice up Barbara, you may want to instead consider Varvara or Barabal.
