Parallel Quattros - Dual Shore Inputs on Input #2

Proposed Layout:
2 x Quattro 24/8000/200 230V parallel setup for 240 Split Phase with AT

AC-IN-1 on Q1/Q2 units is generator - split equally.
AC-IN-2 on Q1 is Shore Input #1
AC-IN-2 on Q2 is Shore Input #2

Heres the hypothetical question - in this configuration, if i was to disconnect a shore input on either of the AC-IN-2 lines would that unit slave over to invert and the other unit continue pass thru if its AC-IN-2 still saw power?

Basically can Parallel quattro’s run in different ‘modes’ while setup in a master/slave relationship?

Have done lots of 240 split phase installs similar but only with splitting 2 ac sources equally between the units - wonder if the configuration above is possible?

Both AC shore line inputs would be 240V/60HZ no fundamental differences in voltage or frequency.
