FFT Golem doesn't work when you're Innocent (it runs off your Magic stat and Faith just like any other spell, it just has a super-high base hit rate), which is a good case to say FF5's doesn't either, even though it technically doesn't run off any magical stats. The same can probably be said for Quick and Return.
The problem, for me, is Spellblade. I'm not really inclined to see Innocent turning that off. It is not based off magic stats, and unlike Golem doesn't have an FFT analog to call it Faith-based... in fact it is closest to FFT swordskills. The only thing which gives me pause is that is vulnerable to Silence, but eh, so are Truth and Talk Skill in FFT, and those aren't Faith-based, so I don't think that's good enough. Of course, this just forces Ramza's reaction into Blade Grasp or something like that, which should give him the time he needs.
Can Ramza kill in time, though? He'll get three more turns after the Innocent, but can't use Magic and his secondary is locked, as is his hat and he needs something to hit 10 MA... although wait, Bracer goes a long way. Yeah, think that's good enough, Power Sleeve Bracer Rune Blade Thief Hat gives him the PA, the MA, and the speed he needs, here.
So near as I can tell Lenna needs to have Quick or Return work (Quick's extra turns let her punch through Blade Grasp in time, Return is obvious), or Golem, but since Innocent explicitly shuts down all Time and Summon in FFT, including analogs to two out of those three spells, I'm not inclined to hype this. Alternatively you could let her Defend, but I do not.

EDIT: Okay, one other angle I should actually look at is Lenna using Lamia's Tiara, which trades away status immunity and a bunch of speed for 5 MDef, which given the dangerous zone Doubt Faith resides in could be critical. It does leave her open to some status, but the most accurate one which would be (very) deadly is Silence Song (which can also be blocked by a robe, but that would undo the MDef benefit). The questions would then be if Lenna's MEvade could save her from that, and that depends a bit on how much you respect an MEvade stat the entire cast has, as well as how much you respect an MDef push from a universal option (i.e. if you averaged it in, there's no change at all!). I don't think this changes my vote but it's something to think about.
Final four has had some excellent matches honestly, even if I suspect they'll all end up blowouts because we convince each other too damn well. <_<
