I wouldn't worry. Pachuca has out-classed every team this tournament with 2nd stringers and now they travel with a full squad (saw the official traveling report) for this match. Even if they decide to play an alternate lineup, most of them will be the usual starters which should be enough to win. They already beat Olimpia with 2nd stringers so I totally expect them to dominate this match regardless of the starting lineup, they're loaded in every position! I guess there's no harm in waiting for the starting lineup to make your bet a little more safe!

As of the Toluca game, one of their second stringers just gave an interview admitting "even though we are playing with a lineup that doesn't see regular playing time blah blah", they're clearly thinking ahead on to their weekend match.

As of Cruz Azul, I can't argue with what you're saying lol however I do know coach Tomas Boy tends to take this tournament seriously unlike most teams. My guess is he tries to disguise his failure on the Liga MX with a couple of Cup wins! Just check the trend, whenever Cruz Azul f's up during the weekend, he plays regular starters for the Cup and has been doing this ever since coaching Atlas!
