Transistors do not play well together. If you connect the B.s together and the C.s together and the E.s together they will not share current.
If each transistor had its own emitter resistor, and the resistors had 0.3 volts (or more) across them at full load then they do some sharing. At 0.6V on the emitter resistors they play together fine. The transistors need to be at the same temperature. (on the same heat sink)

That's for bipolar transistors. But MOSFET transistors can have a significant difference in Vgs for the same current which makes balancing them even more difficult.

A dirty solution for this might be using same number of opamps to get each mosfet be part of their own feedback system.
Still, an emittor resistor is needed.
