It doesn't take much to turn it in a deluxe minus the automatic turn single's.
That's what my dealer did when I bought my 2013. He took Honda's $1,000 'bonus bucks' and installed the OEM backrest, heated grips, and center stand. Since he couldn't add the turn signals he installed the 12 volt power port instead. That's just as well as the self cancelling signals cancel too fast. It worked out great for me. Today there might be a problem be finding a backrest, but the other items could be added easily.
I just did basically this. Bought a leftover 2016 F6B, had the dealer add the centerstand. I had to find a passenger backrest on Ebay and paid a LOT for it, but they are getting pretty rare.
Since I live in Texas I haven't looked into the heated grips yet... Definitely intend on adding them in the cooler weather. You can get there (minus the turn signals) for less than the $1,000 difference a Deluxe costs.
