This is exactly what I did, and for the same reasons. Perfect for offline reading on the NYC subway. The only thing I am missing is sending articles from the Feedly iOS app directly to the Safari Reading List.
Edit: Feedly problem solved by switching to Reeder 2, which is a way nicer app anyway. Yes, it does cost money (currently $4.99), but I use my RSS reader every day, so this is money well spent.
