You are going to get a secondary fermentation. I don't know how much sugar is in there, but if you are using a secondary 5 gallon carboy for a 5 gallon batch, you may want to stick a blow-off tube on there just in case. I have had explosive secondary fermentation from fruit in similar situations.
Regarding the coconut and oils...I have had mixed results. I have changed my recipe a bit over time to improve head formation and retention, but even the first time I made it I didn't *really* have issues with it to the point of there being no head...more like it dissipates a bit faster than I'd like.
