Wanted to get this in before the deadline. This is starter and backup, at their peak season as an Astro (not career, not on other teams) and can't be repeated (i.e. no Biggio at C/2b or Berkman at OF/1b)...
C Biggio / Cliff Johnson
1b Bagwell / Yuli
2b Altuve / Bill Doran
3b Bregman / Ensberg
SS Thon / Correa (Dickie should have won the MVP in 1983)
OF Berkman, Cedeno, Hidalgo / Wynn, Springer, Tucker
DH Yordan / Beltran (he didn't play long enough to merit more than this and no way he's not in the field but he was so good you gotta put him somewhere).
SP Nolan, JR Richard, Mike Scott, JV, Dierker / Clemens, Hampton, Cole, Keuchel, Randy Johnson (see Beltran)
RP Wagner, Dotel, Lidge, Sambito, Larry Andersen / The 2022 bullpen
