I realy like the idea of every one getting a cool power up form, especialy both Issei and Vali achiving Sub-Species Balance Breaker when going up against foes like Euclid and 666.

However, against Rizevim Issei would probably have to focus on using his Demonic powers and Dragonification, say like he gains a form were his body gains reptilian scales and even his wings become a cross between devil and Dragon with his physical abilities increased. Although, first I think he needs to better control and increase his magic abilities before he faces him. And maybe he could use some Holy object against him or being able to use Holy magic seeing how it's less likely to hurt him in his new dragon body.

Maybe he could enhance his Dragon Shot with his Dragon Flames and create something like "Dragon Flame Shot" or something like that.

These are  just some ideas of mine

P.S: Yes I also noticed that his Dragon Shot was similer to Kamehameha seeing how Issei is a fan of a similer anime, even more so when he fought Riser, he use both his hands for it.
