What the heck do you mean you can’t just pasken from the Rema from a Haora on the Mechaber. That’s what he wrote the Haoras for! You think he wrote them for fun? He wrote them so that we know what the Halacha is according to Gedolei Askenaz and so unless many Acharonim disagree – thta’s the Halacha for Askenazim.
