I think you will be better off using 2 X ir2110 instead of gate drive. A gate drive transformer is a delicate thing to do and it has to be symmetrical in all ways with the 5 windings. It also needs to have a high permeability core other wise you will have to do a lot of turns to get to the right inductance. One other thing I want to mention is that if you load the sg3525 more than necessary the wave form starts to deform. On the other hand with IR2110 the wave form comes out nice and clean. For isolation the GDT is better. I guess for a first experience it would be better to start first with IR2110.
I experimented with gate drive transformer and what I told is from my experience.
