Her hair, eyes and everything going on inside her was shifting due to that energy around her so by that conclusion she can go SSJ if she learned to master herself.didn't Gohan tell Videl that in order to fly she needs to look deep inside herself and push the energy she has inside her out?.What if it's the same with this new energy surging through her? Is it possible? Could be.but can it be done?.Why not! I remember watching an episode of Doctor Who where it was made clear that River Songs DNA was changed due to her being surrounded by Time Rift energy while being consummated by Amy and Rory in the Tardis thereby giving her an extra DNA strand, giving her the ability to regenerate and harness Time Lord abilities.so why not for Videl? Think about that for a moment. Thought and other Mental influences as well as outside influence can alter you without your realisation.now all that energy that was pulsating around Videl could have somehow altered her own and therefore her DNA was changed, due to her unborn child carrying Saiyan blood, and in that moment while everyone was connected they were all sharing the experience thereby exchanging matter, protons, neutrons, electrons, photons, alpha, beta, gamma particles around and the claim that radiation and energy changing DNA proves sufficient enough to suggest that Videl was altered in that moment. In the series, Cell is a supervillan and an artificial life form created from the cells of main characters in the series. New science has proven fact that radiation and cosmic energy can alter and change DNA.so the idea of Videl going SSJ isn't that farfetched as you might believe.
