Unfortunately I don’t know any of these shows.
Reading your linked website seems to indicate that the order in which these were originally broadcast is not consistent with the order in which they should be watched. Am I correct in this assumption?
If this is the case, I’d look to modify the original air date of each episode so this air date does create the “correct” episode order.
Then you can apply this trick to generate a smart playlist, which you can use to watch the shows: Watch crossover episodes of several series in-order
