I think a trade of Rendon for Yelich is about as equal as it could be and I don't think the Angels would be interested in eating any of Rendon's salary or adding a prospect or two to the deal. Overall Yelich is going to cost more than Rendon when taking in his whole contract compared to Rendon. Also it would be three years early not two for the Brewers. Yelich is eligible to be a FA in 2030 and Rendon in 2027. I think at most you could get about $7-10m in salary relief from the Angels if you needed more you would have to add prospects. This would be without the Angels sending any other prospects over.
I would rather live with resigning Jace and having him platoon with Urias at 3B than trading Yelich for Rendon. That wrist injury could kill all of Rendon's power and then you are back to what the Brewers have with Yelich.
I still think Baltimore makes the most sense for the Brewers to make a trade with if it means trading Burnes. Rodriguez is ready to start in the majors and he profiles as a top of the rotation starter. If you could get Rodriguez, Holliday and some lower level prospects in a trade I think the Brewers have to pull the trigger on that trade. Rordiguez would be able to join the rotation in 2023 and then in 2024 if you keep Woodruff you have a rotation of Woodruff, Peralta, Ashby, Rodriguez and Gasser. It basically resets everything and you have a very competitive team in 2024 with the starting rotation.
The Brewers would then have Holliday who looks like someone who could move really fast in the minors and be your starting SS in 2025 or 2026. The Orioles have a lot of middle infielders in Henderson, Westburg, Norby, Hernaiz, Ortiz and Prieto so losing Holliday wouldn't hurt as much. Henderson looks to be either the Orioles starting SS, 2B, or 3B of the future. I think he probably fits best at SS or 3B and I think they will have him play SS in 2023 so that may make Holliday available this offseason.
