Rum oils and long term aging

[SouthTexasShine]

I've made about 4 gallons of rum, using my 15.5 gallon keg and 7.5 gallon thumper. I have been brutal with heads and tails, throwing then in the thumper for the next run. At this point I have about 3 pints of white rum oils that will go back in to the next run. Here is my question, the hearts I've saved have a good rum flavor and smell, but not the depth I'm wanting. I want to get to 7.5 gallons at 68% and age it for between 6 and 24 months in a pony keg with a piece of used barrel stave that has been charred on all sides. Would it make sense to add a goodly amount of the rum oils to this batch for mid to long term aging. I'm looking for a heavy rum, not a Bacardi silver clone.

Thanks
