I don't think "overnight replacements" are a good way to improve immigration; a series of quick hacks is largely what got us into the current mess. As for a specific replacement, I'd support a Canada-style non-sponsorship-based points system. Although I think there is something to be said for just randomness as well, such as expanding the Green Card lottery. Many of the immigrants who made large contributions to U.S. society/economy did not come in already highly educated/skilled, so I'm not sure it's a long-term advantage to restrict immigration to primarily people with strong pre-immigration skills/credentials. Short-term yes, since it fills shortages in areas of the economy, and I think a points system is a good way of handling that without the unsavory employer-tied aspect. But longer-term the "American dream" idea is that people should be able to gain those skills after immigrating; you can come in without already being the kind of person who can command six-figure job offers, and work your way up. Historically that's where a lot of the benefits of immigration have come from.
