yes, now you display you understand what it would address (a good design that delivers clean sinusoidal wave forms for all combinations of output power -which sum to smaller than or equal to the total supported power, a square region of power combinations- would be non-trivial but is theoretically absolutely feasible without energy storage elements [other than small ones for stepping up or down, control etc])
it would be nice if a flexible (supporting all operating points in the power square) 1 DC-in 2 AC-out quadrature voltage storage-less inverter had an open-source design.
[One can not make a single outlet sinusoidal without equivalent storage capacitors / inductors, its simple mathematics, constant DC average power in - clean AC power out = power stored and released or simply wasted in sinusoidal oscillating fashion (regardless of implementation).
to avoid storing energy, while requiring clean sinusoidal output, 2 AC outlets is the lowest number of output outlets that admit an exact solution since the sum of 2 power sinusoids in counterphase result in a constant output power.]
the power operating point square is delimmited by 0 and 1/2 total power for each AC outlet.
