yeah ofcuz captains in Royal Guard become more stronger...not just them but senior captains in Gotei 13 too (Yamamoto/Unohana/Kyoraku/Ukitake)...I don't think Tenjiro or Senjumaru or Hikifune are more stronger than Yamamoto...maybe if Royal Guard vs Senior Captains of Gotei 13 against each other:

Royal Guard Team= Tenjiro, Senjumaru, & Kirio Vs Gotei 13 Team = Unohana, Kyoraku & Ukitake

i doubt it hard to choose which team would win...maybe RG would win with their upper hand skill (healing water, guard and reatsu food)...but who knows Uno/Kyo/Uki pretty powerful too and their bankai ability still unknown...
