I mainly ask because I can't really think of it either. What could be really useful to him? That last option sounds a little too much like Zenith Tempest mixed with Excalibur Mimic. Maybe a more aggressive absorption ability? Since Sacred Gears can take on abilities, like Divine Dividing, maybe Issei could get something like he copies and uses other peoples Demonic Powers.

What I thought also might have been interesting if perhaps instead of just transferring power to people, the sub-species of Boosted Gear would boost body parts, and decrease as the "power" is used, similar to Rias's Bust command. After all, its sort of insinuated that the girls in the future get very "ample", maybe that what's caused it. I thought it would be interested, because it would be like Sirzechs putting the idea into Issei's head, and the idea turns his Boosted Gear into a sub-species.
