You should be able to use J.R. Richard, too, just because. 
A few starters for others:
1B Lou Gehrig, SS Lou Boudreau, LF Lou Brock…
1B Fred McGriff, SS Freddie Patek, LF Fred Clarke, CF Fred Lynn,
P Eddie Plank, 2B Eddie Collins, 3B Eddie Mathews,
P Frank Tanana, 1B Frank Thomas, 2B Frankie Frisch, SS Frankie Crosetti, LF Frank Robinson, RF Frank Howard
P- Sudden Sam McDowell, OF-Sam Crawford, OF Sammy Sosa, OF Sam Rice
Eddie Gaedel, PH
NOW we’re getting somewhere!
Eddie Murray at 1B.
Hall of Famer Billy Hamilton played outfield as well. If you’re using Willies, Will Clark might be a step up from Bill Buckner.

Man, I’m blanking big time on some of these positions – I shouldn’t do memory work on a Monday. Maybe not the greatest team of all time (and a lot of Dodgers), but a decent start.
Steve Howe, if you can keep him clean.
OF - Steve Kemp, Steve Finley
P - Steve Stone
1B/DH - Steve Balboni
Others I thought of between submitting my post and falling asleep last night:
SS (one of the several spots where I could play him): Michael Young
C: Mike Napoli (amazing neither of these Rangers came to mind so soon after the World Series)
Utility (if I were to fill out a 25-man roster): Michael Cuddyer
Player-manager: Mike “King” Kelly (Hall of Famer from the 19th century)
Additional arms: Mike Krukow, Mike Norris
1st Base: Pete O’Brien
2nd Base: Pete Orr
SS: Pee Wee Reese

Catcher: Petey Paramore
Pitcher: Pete Harnisch
Reliever: Peter Moylan
2B George “High Pockets” Kelly
C George Gibson
I cheated and looked guys up because of the plethora of Willies and Willys who aren’t named William. Will Clark is actually a William, so he counts. We can move Buckner to the outfield. The lineup now:
C: Bill Dickey
1b: Will Clark
2b Bill Mazeroski
ss
3b Bill Madlock
OF Sliding Billy Hamilton
OFWilliam “Swish” Nicholson
OF Willie Horton (Det)

No idea who the starters are.
Modern-day Jeff starting pitchers could be: Niemann, Karstens, Suppan.
None are particularly awe-inspiring.
