Too good advanced exercise

I use the position below as one of many positions to demonstrate when it is too good to double (or redouble). Good players should have no problem seeing that this position is too good.

Now, here is the challenge. Yes or no answer. Is there anywhere else on the board, either together or apart, that you can place the two remaining blue checkers where it would not be too good to redouble?





White is Player 2

score: 0
pip: 76
Unlimited Game
Jacoby Beaver
pip: 12

Blue is Player 1
XGID=-a----B------------cbcbbb-:1:1:1:00:0:0:3:0:10
Blue on roll, cube action?
