Saji can fused the Sacred Gear but for it to become a Longinus would be a bit impossible since it lacks in power. Well that's also why i said to fuse both Kiba's SG + Demon Sword into one, to power-up his Sacred Gear with the Demon Swords and uncursed the Demon Swords with the Sacred Gears, also allowing his SGs to transform into a Longinus.
