Simulate center-tap transformer using two transformers?

I have a PCB that takes 3 input terminals: V-, GND and V+. On the manual, it is stated that the inputs should be two 6V outputs from a center-tap transformer. I do not own a center-tap transformer, so I'm curious whether I can simulate a center-tap transformer using the following configuration:

Consider two 6V transformers A and B.

Connect:

A- to V-
A+ and B- to GND
B+ to V+


Would that be electronically sane?
