Do you know the make and model of the -15 bag?
From my experience you're probably a little light on insulation... not badly light, just a little light. Adding a heavy polarfleece liner would help inside the bag if you have room, or if the bag is synthetic insulated maybe adding another sleeping bag or a blanket on top would help (if it's down you'd just compress the down and be worse off than you started, IMO) Your hammock has the top cover panels right? Those will help.
I sleep reasonably warm, I use an oversize -30 bag with a polarfleece bag liner, with a DD Underquilt (think synthetic underquilt about the size of a backpacking 15 bag) which handled -13 or so just fine last year. Adding a IX insulated hammock sock this year just for headroom in case it gets COLD.
