Convert multi amino acid sequence file (.faa) to nucleotide sequence file (multifasta; .fa)?

I have a .faa file that includes gene sequences ~714 individuals. I want to convert this to a nucleotide sequence file (multifasta; .fa) so I can use SNPs to make a tree. Is this possible?

not much, the conversion from aa -> nucl depends on codons, some aa has 6 possible codons, how do you choose the original one?
