I see that staging is accomplished by by the conical thrust core, which is designed to keep pressure on the lower side until close to burn-out, at which point burn through occurs and lights the next stage, which then thrusts itself out of the BT of the previous stage... since the transition occurs while under thrust conditions, flight path should not deviate too much... but you'd really have to load the nose for balance to the final stage and the finless design...
