I certainly get what you're saying, but as someone who's coming up on 7 years of happy marriage myself, marriage is just the beginning of the story really (as you also know, I'm sure). She may not be the source of drama directly, and I do agree that something is lost in that, but what's gained is them facing whatever comes.. head-on, side-by-side. I love the maturity of that, which is pretty fitting for Superman's demeanor. Given the number of characters who aren't married, there's a lot to be mined. Lois is still very much her own person, who was chasing stories as "Author X" - she can still chase those leads while Clark is adventuring, teaching, or even just relaxing with Jon. There's a lot of story potential still there, some that wouldn't have the same impact in a different situation.
The Bat-Suit was a neat idea - building her a set of Kryptonian armor for those times when she needs it would be pretty cool.
