Ideas for abyssal map flier team

First three members are S.Takumi with brave bow, Est 4* merge using galeforce with heavy blade in A-slot if necessary, and singer/dancer (probably NY Azura for the hone). I wanted L.Ryoma to be the fourth as a second galeforcer but I'm having trouble making it work. I did some homework; 70-80 atk is what a non-quad galeforcer will generally need to one-round without triangle advantage, which sounds absurd but (that's what abyssal mode is and) fliers are OP so I think it should be doable.

Conditions for this build: one-round galeforce KO a red with 87HP, 35 def, 37 spd, and no swordbreaker. (That's actually a standard statline on melee infantry in abyssal - 37/37/35/27 with 82HP before skills and weapon refine.) Bonus points if it can do the same against 39-41 def. Maximum support is hone fliers + one goad + drive atk or drive spd because I need him to be able to charge ahead of Est to set up triangle attack, and I think I can set S.Takumi up to goad him.

I've been looking at this but I'm just scared of using brave weapons that aren't bows because I'm not familiar with how it plays out. It looks good in theory, but what happens in a real map might be different, especially if on any given turn I can't get the hone onto him.
