I don't think it would be possible for a half-Ghoul to become a full Ghoul. Though the Ghoul traits are mostly dominant, they are still partially human and I don't think it would be possible to completely erase that from them.

As for the whole "stronger" piece, besides being explicitly told they're superior as a result of Hybrid Vigor we've been shown that they seem to be able to increase their power faster than a normal Ghoul could.

Based on what we've learned with the Tsukiyama family having a genetic defect related to their RC cells and the kakuja mutation.....I imagine that is where the whole Hybrid Vigor comes into play. The full Ghouls with Kakuja seem to have been long-term serial cannibals with years of doing it. On the other hand, Kaneki and Takizawa both have incomplete Kakuja within a much shorter period of time and Eto's kakuja is the most advanced seen in the series. So likely, their greater genetic diversity makes it easier for them to not only increase their power but to become a Kakuja.
