3 gang box makeup

I am taking a two gang box out and putting in a 3 gang to accomodate a new fan switch.

THe current box has four wires - a feeder from the panel, traveler to other outlets, and two switch legs. Now I am adding a fifth wire (14/3).

What would be the best way to tie everything together? I think I am going to have to get creative since I will need some pigtails, etc and that takes me over the 4-5 fill on a red wire nut.

how would you suggest I makeup the box?
