Hey LM!
Sorry for not getting back to you earlier on this!
The answer to your question is yes! You can air dry and smoke the two recipies together.
However, the six-hour brine time for the dry cure is usually followed by a fresh water rinse and the air-dry clock starts then. So, you'll have a little bit of a time lag between the two recipies.
Start the dry process first (you mentioned six for the dry vs one for the soy so five hours before right?) and then air dry and smoke the two together and tell Tobeck and I when it's done!
