Sure, but why couldn't we just call the value of a reserve day (4:17:39) LPV instead of MPG? Make it all the same bucket and then you'd be free to mix and match at will. I personally would love to see composite reserve/line hybrids here at UAL, I just don't think the masses will ever care enough to get it into a contract. Too many people are content to just fly their lines. Nothing wrong with that, but I think there's QoL to be gained by increasing options available to everyone.
