yes! no Claude!!!!
Or better, heaven help Claude when she finally meets him again!
I think you should stay as close as possible to LnC canon. This Lois can avoid a lot of the pitfalls that the original one committed, but she will still have those memories, so she knows what she will need to do to get to where she will meet Clark.
This Lois should still not be 'in the mood' for mood pieces, this Lois should be still able to strike fear in people. This Lois should still be able to take no prisoners to get her story.
But...
This Lois will probably have one extra Kerth. This Lois will have a better relationship with her father. This Lois will probably be friendlier with Cat(she won't be so uptight about her social 'failings'). This Lois will probably play it cool with Clark, for about, oh, 5 seconds

. This Lois will not fall for Lex (Which can be dangerous, since she will want to take him down a peg at some point.
This story opens all kinds of possibilities.
As for the paradox issue...This Lois is a refugee/orphan from a now defunct time line. Similar Frank Parker of
Seven Days. Once he fixes the problem, only he will remember what actually happened.
James, whom you can tell really likes time traveling stories.
