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, who seem to focus mainly 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 not even he let himself be affected. He still killed "the one who helped him develop his powers", only because he was a threat to Ichigo.
