Scrap Orthros + Green Baboon

Ok so i have a green baboon in my hand, a scrap orthros in my hand and a scrap beast in the feild, along with a chimera in my graveyard. if i special orthros, destroy beast, and activate green baboon's effect, do i miss timing to activate scrap beast's effect to get chimera from my grave to my hand?

All those effect will form into a chain, follow SEGOC's rules.

Scrap Beast on field, Special Summon Scrap Orthoros and target Scrap Beast.
Scrap Orthoros destroys Scrap Beast
Scrap Beast's optional trigger effect activate, chain Green Baboon's own optional trigger effect. (you can choose which card you want to place on chain link 1)
Resolve the chain, no timing missed.
