I'd keep the same judging panel conditional on:
a) Len leaves DWTS, or DWTS reschedules their program so it doesn't clash with SCD.
b) Alesha, Len and Bruno are told to use the entire range of marks they have.
c) The judges are given some camomile tea or valum before semifinal and final so they don't get overexcited and go 10 crazy.
Otherwise I'd replace Len with Ian Waite, and Alesha with Kara. I just think Kara will have the same amount of sympathy with contestants, but she is able to be more critical of them.
I'd also keep Bruce, but give him more room for improvisation. I think that's his area of strength and he's clearly too old and doddery to keep up with the uninspired autocues he's supposed to read.
Use Anton to replace Bruce for the result show, and Claudia to replace Tess. The result show doesn't need to be as glamorous as the main show, so we won't be needing a tall blond presentor turning out cliches after cliches! Or even better, completely replace Tess with maybe someone like Cat Deeley.
Keep the same pros, but I wouldn't mind James and Ola replaced.
ITT with Zoe. If Ian isn't on judging pannel then I want him back on ITT for Wednesday's Waites! Otherwise use one or both of the Jordans.
