Don’t forget that if both feed valves are open, and there is no air in the piping the top feed lines from both tanks are in fact a “crossover”, and will equalize the tanks as a siphon just as surely as a bottom connected crossover. You do in fact have a “crossover”, with the advantage that instead of draining both tanks into the bilge everything will stop if something in the crossover piping breaks.
