I have my 20 week anatomy scan on the 29th of this month and we get to find out the sex if the baby cooperates that day

DH unfortunately cannot make the appointment due to work, he has to run the office while the other manager is out of town on his honeymoon. His office luckily is only a couple of miles from where my doctor is so after the appointment I was thinking of driving over there to tell him what we are having as long as I find out, update him and give him a sonogram photo.
I was wondering if anybody had any ideas on how to tell him if we are having a girl or boy? I thought of having a t-shirt made up and come into his office wearing a t-shirt, put a boy or girl onsie in a gift box for him to open? We bought little baby Adidas Sambas and I have pink/blue laces (I am using the shoes for our gender reveal on fb) I could put those in a box/bag too with the corresponding lace color for him to open since I already have them.
Any other ideas/suggestions on how to tell him right after my appointment?
