I think the gem in Loki's scepter is another stone entirely, could be the blue mind gem, which will make sense that it is in Avengers: AOU and I think it will be the basis of the Maximoff twins' powers.

For the power part, I think the Red Skull only converted the energy of the Tesseract into large blasts of energy through weapons, not the whole Tesseract itself, wherein the Aether itself could destroy whole universes by it's power.
