That's about right. You shouldn't need the transistors at all.
I wanted to make sure to lower the coupling ratio...so I used the minimum.

I have the surface mount and the through hole version of the PS2501-4 and basically all the surface mount version is, is just the leads bent parallel to the surface, so no real weight savings.

The schematic I was working on had an extra trick, in that it was designed so you could test the circuit end to end without any tools. Figured we had enough people nervous about going this route that making it 'self test' was a the best solution to calm the nerves.
