That would be about the worst plan ever, Issei growing stronger to dragon god class is common sense by this point, with his popularity plus backing from Gremory, Phenex, Zekrum Bael, Ajuka, leaders of grigori, heaven, youkai's and Shiva plus all his accomplishments no one is going to turn on Issei no matter how fast he grows

Indra is by no way allied with hades he just wants to make war with shiva and if anything might be trying to get Issei on his side like Shiva attempted during the high class promotion, there's no proof of that
