Okay, that's a decision. I don't know how fast your workshop is working, or how long it has to wait for the new wing, etc.
I had a wildlife accident exactly a year ago and needed a new front wing. The car went to the workshop in March and came back in September due to various waiting times.
My recommendation is to ask the garage how long it will take. I wouldn't give the car to the garage until the replacement wing has arrived so you can drive in beautiful spring.
