Ed,
As long as the transformers have the same output voltage faceplate
rating you should have no problems mixing and matching. They do not need
to have the same output current ratings. You should verify that each
transformer works independently (by drawing arcs from each bushing to
the transformer's case). Don't connect a transformer that's got a "weak"
side, since it'll reduce the output of all the others when you connect
them in parallel. There's no need to actually measure the transformer's
output voltage.
