It is known to work in ordinary non-linear transistor-based mixers. It 
will produce more messy spectrum than double-balanced mixer, however, for 
this purpose and completely within digital domain, it makes absolutely no 
harm, in my oppinion. On the other hand, simplicity of two resistors & ADC 
may help.

If in doubt, let the original poster try this and send us the data for 
analysis. (Mailing-list or personal e-mail(s).)
