I think there are two truths that need to be acknowledged.
1) The Brewers are never going to match up "on paper" with the Dodgers so long as the current economic system is in place in MLB. The Brewers are going to have to get lucky to make the World Series, much less win one.
2) Per what I quoted above, in 2016 the White Sox had two All-Star starting pitchers - Chris Sale and Jose Quintana. They traded them for packages that included Michael Kopech and Dylan Cease. While Sale and Quintana had two more good seasons each, neither proved to be worth a big contract. The Brewers are going to have to trade Woodruff and Burnes for packages that include some young high-upside pitchers that could potentially replace them. Yes, Woodruff and Burnes can be replaced with similar talent.
The question is when.
For pitchers, it doesn't have to be in the offseason - they are arguably worth as much if not more at the deadline, so there is no harm in going into 2023 with both and then seeing where things are in July. (Quintana was a July trade.) The risk is if one of them gets hurt or regresses (which we could be seeing with Burnes now). But there isn't a need to trade prior to July, 2023.
We saw the lack of CF options at the trade deadline this year. If Mitchell and Frelick (and Ruiz) pan out, they can trade one of them for a haul. Adames has his faults, but among the 30 SS with at least 200 PAs this season he's 8th in WAR - they can get a significant return for him too.
What the Brewers need in 2023 is:
A healthy Peralta/Woodruff/Ashby
Burnes to find his 2021 form and cutter
Ashby to take a step forward like Burnes/Peralta did
Hiura to replace McCutchen's ABs and continue what Hiura has done in the 2nd half (2nd half OPS .871)
Yelich to continue his .400 OBP (2nd half OBP .389) and find his 20-25 HR stroke
One of Mitchell/Frelick to be a >2.5 WAR CF
Williams to be comfortable as the closer and Rogers back (and his ERA matches his 2022 FIP)
Either an upgrade at 3B or (more realistically) a Peterson/Brosseau platoon at 3B with Urias in a super sub bench role
Better offensive production at catcher (Caratini 2nd half OPS .443, Narvaez 2nd half OPS .505)
It all starts with Burnes/Woodruff/Peralta/Ashby and the back end of the bullpen - those are the horses they have to ride.
