Personally, I want to just do a reboot.
Pretend Superman Returns never happened the same way Superman Returns pretended parts 3 and 4 never happened.
No kid. New Cast (mabye). New Director (definetely). New story (definetely again).
I would love a reboot but that is completely unrealistic at this point. WB had their chance to do that and blew it.
The next best thing to do is for the sequel to not refer to the previous movie and have life in Metropolis back to normal...except that both Richard and Jason still exist (Damn you Singer) but I wouldn't show the kid, maybe a quick mention by Lois that she has to pick him up from school.
Since the love story is screwed up at this point between Lois and Superman. I would introduce the beginnings of a love triangle between Lois, Richard, and Clark.
As Lois prepares to marry Richard, she realizes that she has feelings for Clark, and has for quite sometime, but her preoccupation with Superman always overshadowed them. With her feelings for Superman finally resolved, she finds her feels for Clark go pretty deep and she allows herself, apprehensively to look at Clark in that way.
However this is just a method to deal with the presence of Richard and only a minor sub-plot in the movie.
The major story should be the arrival of Brainac and its alliance to Luthor.
If WB brings back Singer, and he goes with Zod as the villian, that will be the deathblow to this series and we won't see another Superman film for at least 8 to 10 years.
