I dunno what danger they could pose to the Sternritter. But given that they're powers are intact and the same as before they were killed, they could do some damage.


 * Ginjo is at least part Shinigami and has a Bankai, and he has some power.
 * Giriko can become huge and muscular, he could perhaps take on someone like Mask De Masculine - he seems to focus on physical strength.
 * Tsukishima can insert himself into the past of his victims, so he could be very dangerous. The problem is that I doubt any of the Sternritters would refrain from killing someone they supposedly "share a past with".

Byakuya was affected by Tsukishima's power, but he still killed "the one who helped him develop his powers", only because he was a threat to Ichigo.
