Alex didn't replace the Wendy and Dipper romance with the idea of Pacifica and Dipper. Literally the only episode in which Dipper and Pacificia interact for more than one or two lines is "Northwest Mansion Mystery" and that episode hints at nothing romantic between the two despite what the shippers says.
