Hello, thank you for your respectful response (love the community this game has)
I did read your full post and sad to say not a fan of either ideas, second point first about due conveyor belts, for me this ruins the game by removing a lot of conveyor belt issues and isn't actually needed, let's go back to the first point
For me alternative recipes are amazing but no to replace your current setup if you don't want to, but for creating smaller factories to join your main base. An example would be my megabase has 6 builders for each component which is spreading its products were needed around my base. Although heavy frames need lots of resources and would affect my base too much, so decided to create two smaller bases near my coal conveyor, this is where the alternative recipes really show their use, when creating whole mini bases and make adventuring into the wild more interesting to find the hard drives
The power it uses doesn't work to balance unless it was really high, but if you really wanted to use one conveyor would need a super-comupter merger to join the two different items. The conveyor would only ever contain one item at a time, so would need to clear one item before the second could join. But like I mentioned earlier this for me is not needed
