So, if - let's say - Lois Lane and Clark Kent marry, which will be the family names? (I'm asking for options, not for the acutal case!)

1) Both keep their respective name.
2) Lois Lane becomes Lois Lane-Kent or Lois Kent.

What I want to know: Is it theoretically possible that...
3) Clark Kent becomes Clark Lane
or 4) Clark Kent becomes Clark Kent-Lane (or Lane-Kent, for that matter)
5) both take the name Lane-Kent or Kent-Lane (can they even choose differently, as in Lois Lane-Kent and Clark Kent-Lane?)

Thanks in advance!
