Tank, I love this idea!!!
I see two very reasonable endings.
First, you could have Lois 1 be sort of a Linda King variant that has some elements of Lois but much nastier. She could be someone that is always used to getting her way. She's always taken things and left the scraps for her sister. She's the one that is convinced that Superman will fall for her if she just figures out the right approach. The other Lois can be a slightly mellower version of our Lois. She is used to winning against everyone but her sister. She would be the one that Clark likes and she's the one who finally decides to settle for Clark.
If you make both the Lois's nice, this:
OK, but if you do this, you have to have at the plot twist at the end that losing Lois finds love with alt-Clark. We can't a Lois without her Clark.
is a great idea.
