Not really. If there is anything explicit in Isaiha 1, Psalm 40, and Micah 6:6-8, it is that offering, assemblies, and religious observances are worthless. He says He is sick of them. He says he has no need of such things. What is preferable is not child sacrifice but justice, kindness, humility, ceasing to do evil, correcting oppression, and helping those in need. But what we can read in the Bible, is not that religious observances have any innate value, but that God commands them anyway. Their value is not to God but in the effect they have on us. They are a way to make an effort when we feel helpless to do better in any other way. Making an effort is important even when it is worthless.
But let us not lose sight of the big picture here. Though I disagree with you on the details, which is hardly surprising, I am certainly not trying to get you to tow some line or believe that the Bible and Christianity have no flaws. After all… I am coming at this from the opposite direction with the presumption of my liberal upbringing that it is all nonsense, to seeing that it does have value after all – to see that there is value in it despite the obvious flaws.
