why take it out?
remember the idea is to "build" your crescendo.
to do so, you add the instruments gradually. there's no need to remove them.
by the way, I see two bassoons and a staff for contrabassoon, but only one flute, one oboe, and one clarinet... any reason for this?
if you are going to answer "they're playing in unison"... don't.
go immediately to my masterclass on orchestration, lesson 1 on woodwinds, and don't come back until you've read the whole thing.
I'd suggest that your woodwind chord should be fuller, and involve notes a bit higher than you have here.
