I'll watch the rest later (Atm I'm tired and my eyes are on fire from labbing hard af lol) but I did a starter like yours with 4,3 but I ended mine into a second "Setup" (all this is just concept though). I did 4,3~Crown, b+2 (they get hit into the freeze) b+3,2 d+1, 4,3~crown. They get knocked back and stand on top of another bomb.
