^ The only reason on why Railgun was able to destroy the windowless building was because Mental Out decided to lend her some pointers AND give some of her own power just to magnify and significantly strengthen her own electrical cannon blast. '''Therefore, your statement can easily be proven otherwise. Index (in John's Pen Mode) managed to severly injure Style Magnus and most importantly Touma Kamijou. Railgun couldn't do shit against any of those people.'''  As such, with that form of evidence alone, I'm quite sure that Index can destroy the windowless building AND obliterate half of Academy City without even trying if and only if she had her full-fledged powers unlocked.

You do realize that in a fight in NT Volume 10, Mikoto defeated Touma. Unlike your normal comical battle between the two, it was a real fight. Although, it's pretty much implied that Mikoto can end their battle in the snap of her fingers had she decided to kill both Touma and Othinus using her hacked Five Over.

As for Styl, I'm pretty sure that Mikoto would stomp him in a battle. Not only did she fought toe-to-toe with a Saint, but she also managed to hold countless tall buildings thrown at her by the High Priest while making sure that the civilians inside of those buildings are safe. Not to mention that Mikoto with the AAA will completely obliterate Styl.

Lastly, there's no guarantee that Index would be able to destroy the Windowless Building in John Pen's Mode. You're simply assuming something without even providing any exact-solid evidence. If your evidence is her dragon breath affecting Touma, guess what, Misaki also did the same thing during the Daihasei festival arc in the Railgun manga. And it is pretty much established that #3 > #5. Now, if you're telling me that the only reason why Mikoto was able to destroy the Windowless Building is due to the help of Misaki by establishing a link between them and carrying half the pain of Mikoto, then the same thing can be said about Index. Index cannot use any of the grimoire through her own will. An outside interference is necessary for Index to activate the grimoires.
