That wouldn't solve any core problem of governance: those bills are an artifact of members of Congress having constitutional power -- the right to vote against a bill. Given that they have that right, they also have the right to withhold it until they're bought off.
If your proposal became law, Congress would still do these compromises, they would just pass the provisions on a different bill -- say, "vote for my bill and I'll later vote for your pork project in the next appropriation". All that would change is the difficulty of coordinating it. The fundamental problem is still there.
