I am not ready to rule out Phillp II despite the difficulties.
The obv portrait appears beardless and youthful
What appears to be an "I" after the "P" (of PIVS?) might be weakness in the strike of another "P."
IMP PHILIPPUS AVG fits nicely in the space and squares with the IM{P} behind the shoulder and with the "I" at the top just before the "P".
The Centaur reverse, with the exergual II, is certainly like one used with Gallienus, and I have not found it for Philip II.
The centaur has no arm reaching up.
Here is the coin Ken is offering:
