Adding insulating layers isn't too difficult but it definitely affects leakage.  The best method I've found is to use calipers to mark a precise width of some thin kapton tape, then cut it to the precise width with a ruler and knife.  Then it is pretty easy to cleanly wrap over a coil.

Starting with an already isolated 48v supply is a great idea.  Your resonant caps might get physically large since you'll need a lot of capacitance.  You also might end up needing a very small resonant inductance, and your transformer leakage might exceed that value.  You might need to prototype your transformer earlier than usually in the design process.
