Replacing The Memorial Acclamation's?

Can the usual memorial acclamations A,B,C and D be replaced with a sung acclamation with different words to those in the Sacramentary?

No. Only the ones printed may be used.

I think there are different permissions given in different countries. Canada, for instance, has the option of different introductions for each of the different acclamations, and I believe there are a few other national variations. Just something to watch out for.
