Then there's the simple fact we've seen Akasha's regeneration ability is WAY above even normal vampiric levels. When she knitted her arm and shoulder back together in seconds, from ribbons, Akuha was pretty shocked. Given Akuha's assassination experience and probable experience fighting other vampires and monsters previously, this should give some idea that this was not normal, and is likely one of Akasha's shinso talents; going down the route/idea that different individuals possess different skillsets, with Shinso vampires probably gaining access to even more extensive skillsets/further developed bloodline abilities.

Essentially Akasha was holding back as was lampshaded in the previous chapter, she's shown extremely potent regenerative abilities, was capable of taking on Alucard with some help, and Akuha never got a chance to finish her off because Moka interrupted the fight.

Pretty solid 50/50 that she could still be going. Even if she can't reattach her bottom half, she may still be able to heal her top half, and essentially end up wheelchair bound (cliche!), either way she may not be dead yet.
