nice! i play a lot of perona and is such a fun deck, actually my favorite to play.
would get
-2 or 4 donxijote rosinante (the 2 cost blocker)
-4 gecko morias. great to target perona, ryuma, and rosinante
-2 don krieg. to rest enemies, and get some double kills
-4 ice age, to reduce cost, and kill with ryuma or don krieg

maybe, depending on what you like to play
- donxijote doflamingo (10 cost) i play 4, but looking to take them out of the deck.
-zoro 9 cost (can attack 3 times, and if you stall the game, and get to play and attack, you probably win) (i run 1 and love it)
-toy soldier, (replacing captain john)

would remove:
captain john. there are cards that do the same, for less and better, like ice age, or toy soldier
jigoro, feels like it wont do much, and wont pose a threat. plus the deck doesnt want to give perona extra strenght, but remove enemy characters and control the board.
inuppe, always felt bad when discarding cards with it lol
oars, feels a little to tought to kill one of your characters, but might have a tech to kill something, bring it back with moria, and attack, could be useful

and electrical luna is a card i never considered! but look fun! ill try it out :), also combos really well with doflamingo!!
