Doing this would be going against what 5ed tries to accomplish. The power comes from the characters and not the magic items he might have. In 5ed, magic is there to enhance the powers of the characters. Making the feats as magical items is just a step toward 3.xed and 4ed where magic was mandatory to rise in power and to follow the power curve required to be competitive with the monsters.
On the other hand, both feats and magical items are optional in the current edition. But not the ASI. If you do go the way where feats are incorporated into magic, I would either raise the number of possible attunements by about two or remove it entirely. This would take some testing but it might work. Characters rarely go beyond two feats anyways.
Don't get me wrong, this is not a bad idea per see, but it really goes against the philosophy of 5ed.
Edit: Changed the word players for characters... I'm nitpicking myself now... go figure!
