Even if you are slotting in Silvie and Gabriela, you're already fulfilling a good portion of buffs already. Yes, you can slot Krantz with those two units. You already have a elemental BB utility, Spark buffs, tri-buffs, mitigation, burst healing, and elemental buffs fulfilled. You can slot in units like Lauda or Faelan to fulfill the BB Atk role, with Lauda carrying more nuking potential like Silvie or Faelan for status ailments. Yes, Lauda and Silvie carry the same BB-on-Spark buff, but they're still extremely effecive given their damage outputs.

You don't necessarily have to be extremely strict in terms of squad efficiency and certain units carrying the same buffs. At times, you're bound to face situations where you'd have to use two units that carry one of the same buff. That's why in Frontier Hunter, you can completely scrap squad efficiency since damage is really all you're going for, such as using double Avant, double Silvie, Azurai, and Zeruiah in the same squad. I even used Zeruiah and Zelnite on the same squad and it worked well in my favor in Kulyuk GGC. The squad still fulfilled the important squad roles and it was able to do fine. This especially goes for players who only have a limited pool of units at their disposal and they can't help but use two units that carry one or two of the same buff. It simply does not make sense to not use a very buff-heavy unit just because another unit carries even just one of the same buff.
