Yes, it is possible. Though then it would have a cushion comb since it would inherit both the rose gene from the mother and the pea from its father.
It doesn’t look a lot like a cushion comb from my experience.
First of all, feather sexing doesn’t work unless you bred a fast feathering male over a slow feathering hen.
Most breeds are fast feathering which is why you thought it was a hen.
Second, are you sure the father was not an Easter Egger?
To me the comb looks like a rose comb with an inverted spike.
