No, that would not give you statistics for the new contrasts.

It's possible to use 3dcalc to obtain them if you know the formula. However, it would be easier to just use 3dDeconvolve. If you've saved the design matrix X in your previous analysis, you can re-run the analysis by adding your new contrasts through option -xrestore. Otherwise, you'd have to run a new analysis to obtain all the contrasts including the new ones.
