Question: has any GM in NBA history assembled two distinct championship teams, on which the best 2-3 players are completely different?
I can't think of one.
Red Auerbach? He basically was the GM all those years.
I've seen mixed descriptions of what his official position was, but OK. You could probably give him credit for 3 different teams, actually.
Anyone else?

General manager (1966–84) Prior to the 1966–67 NBA season, Auerbach announced his retirement as a coach and named his successor, Bill Russell. Russell took over as a player-coach and so became the first African-American coach in the NBA.[2] While his pupil led the Celtics to two further titles in 1968 and 1969, Auerbach rebuilt the aging Celtics with shrewd draft picks, among them Jo Jo White and future Hall-of-Famers Dave Cowens, Paul Westphal, and Don Chaney. With his ex-player Tom Heinsohn coaching the Celtics and led by former sixth man John Havlicek, Auerbach's new recruits won the Atlantic Division every year from 1972 to 1976, winning the NBA title in 1974 and 1976. Further notable Auerbach signings were veteran center Paul Silas and ex-ABA star Charlie Scott.[5]
However, Auerbach could not prevent the Celtics from going into a slump at the end of the 1970s. He traded away both Silas and Westphal because they wanted salary increases that would have made them higher earners than the best player on the Celtics (Cowens), which was not acceptable to Auerbach, even though Cowens personally begged him to give Silas a new deal. When scoring champion Havlicek retired in 1978, the Celtics went 61–103 in two seasons.[5] But in 1979, Boston's fortunes changed when Auerbach set his eyes on talented college player Larry Bird. Despite knowing that Bird had a year of college eligibility remaining, he drafted Bird in the 1978 NBA Draft and waited for a year until the future Hall-of-Fame forward Bird arrived, finally setting aside his team salary rules when it became clear that his choices were paying Bird a record-setting rookie salary or watch him simply re-enter the 1980 draft. Bird then became the highest-paid Celtic as a rookie, with a $650,000-per year deal. Auerbach immediately sensed that the brilliant, hardworking Bird would be the cornerstone of a new Celtics generation.[2]
In 1980, Auerbach achieved another great coup. Dubbed "The Steal of The Century",[9] He convinced the Golden State Warriors to trade him a #3 overall pick and future Hall-of-Fame center Robert Parish in exchange for two picks in the 1980 NBA Draft: #1 overall Joe Barry Carroll, who went on to have an unremarkable career, and the #13 pick Rickey Brown. With the #3 pick, Auerbach selected the player he most wanted in the draft, Kevin McHale, who would also be inducted into the Hall of Fame. The frontcourt of Parish-McHale-Bird became one of the greatest front lines in NBA history. Auerbach hired head coach Bill Fitch whom led the revamped Celtics to the 1981 title.
In 1983, Auerbach named former Celtics player K.C. Jones coach of the Celtics, whom starting in 1984 coached the Celtics to four straight appearances in the NBA Finals, winning championships in 1984 and 1986."
