ADP1048 for 5kW bridgeless PFC

Hi, I am planning to use ADP1048 in a 5kW bridgeless PFC design. I noticed that the datasheet, application note and the eval boards all used three current transformers to reconstruct the current. However, I want to use one hall effect current sensor on the negative AC input line, and what I have in mind is ACS 709 from Allegro which has a +-75A range and 129kHz bandwidth. I'm wondering if there will be any problems using this current sensor? Thanks!
