PJO and the Flash

What if some demigods were affected by the dark matter too? Some demigods without powers got powers and some we enhanced . Annabeth now has psychic abilities meaning anything to do with the mind . Percy not only has powers to control water now but he can create ice and snow and also create earthquakes . He can also produce a force from his hands ( vibrating force like Pied Piper or Skye/daisy in agents of shield ) Other demigods have been affected too . What happens when demigods meet the flash .
Let's say Harrison wells didn't leave the earth with zoom and zoom is out of the picture for now . And the demigods will only stay in coma for 1 month thanks to ambrosia and nectar and being half gods . Starts right season 2 ep 9 and the giant war / blood of Olympus and Leo will be back with calypso .
