I have actually...about 10 times so let me paraphrase my thoughts;
1.. It’s a B-A-D idea.
2. I believe its a M-I-S-T-A-K-E to lock and constrict Superman with even more air tight continuity i.e. The Marriage. It strangles the character and makes him predictable... And that's exactly what a child would do.

4. None of the writers has really figured out how to write Lois Lane, let alone Lois Lane the wife. The fine line that MIGHT make Lois sympathetic does not exist in her current characterization. Lois Lane as it turns out is a very masculine character; her husband is actually the nurturing, feminine side of the family. There positions are flipped. What kind of mother would she be?
5. Lois and Clark are not a team, ala Batman & Robin, and that is one of the keys in the failure to portray the marriage in a sympathetic manner. Lois was created as a Superman Foil, not his confidant & Soulmate®
