MCE and Vox

I will probably try MCE first with RC4 and then my ultamit goal may be to then dump RC4 and use Vox with MCE. Correct me if I am wrong bu this would allow me to use the same computer voice as FO reading the checklist and the same voice talking to ATC for me, is this correct. Would there be any issues using the MCE FO to work Vox? From the MCE website it says it works with default ATC and RC4 but it seems that it can also work with Vox in the above said capacity.No?I am looking at a 2 step upgrade path here.
