Probably - but there is more than one answer since the codon
tables are a many-to-one mapping. Are you hoping for one
possible nucleotide sequence, perhaps with IUPAC ambiguity
characters? Perhaps a specific example of what you want
would help - back-translation is a fuzzy term.

If you are trying to combine a protein alignment with the
original unaligned nucleotide sequences to make a codon
alignment that's a different task.
