In addition, the loadout technology that you're describing tlowster already exists in FC Dynasty, which is a very, very stripped down (and free) game.
I can set lineups to take different formations and/or as part of that I can set as many lineups for one formation as I want (4-3-3or 4-4-2, or whatever) just so long as I name them different things... Typically the way I use this, is I'll have an A lineup with my very best guys and then a B version where I make fatigue subs. The way that game is setup if you go to your Team Schedule you can select which of your lineups you want to use for each future game, or it'll go to the default. It'll be trickier to setup that far in advance in HBD because you're going to want to base lineups around a SP and those don't get locked in until it's the very next game, but still this could help.
