I gotta side with Jay and recommend an S as well. The conversion is already a massive undertaking and will require 110% of your remaining time and motivation. Adding more to the project can quickly torpedo the progress before you even start.
With that said, I will give you one piece of advice and you MUST follow it to a tee:
...ignore everyone's advice!
To take something like this on, one needs to be at least a little crazy / messed up in the head. Go with your gut and do what YOU think is right.
If you are near Lake Orion and want to see one of these projects in person, I'm ~90% done with my conversion. Send me a PM for details.
