Probably not. From the documentation on the EFFECTSIZE option:
"...except for those displayed by the TEST option in the RANDOM statement, by CONTRAST and TEST statements with the E= option, and by MANOVA and REPEATED statements."
Since you use the REPEATED statement to obtain your F values, I would suspect that no effect size estimate will be included. I could be wrong, and the effect sizes appear in the univariate ANOVA tables.
