Pardon my use of terminology - but I will continue to refer to a L fare generically for all individual L fares, two examples which you mention above.
For your 2 examples that you describe, the scenarios may be possible if there are L fares (booking class) with less than a 7 day advance restriction. Are there any such domestic, transborder, or international L fares (booking classes) with a zero day advance booking requirement (or at least, less than 7 day advance booking requirement)?
