Rosewood and the Big block kitchen soap

My original Big Block Kitchen Soap will be changing. Specifically the most popular one, French Field, will be getting, at minimum, tweaked or more drastically, a complete overhaul. Why? the short answer is Rosewood.
Rosewood essential oil is one of the components of the essential oil scent blend I use to scent the soap. Back when I first created this soap, the essential oil was plentiful and I was blissfully unaware of how it was harvested and what could possibly go wrong. I stocked up. So much so, that I haven't really needed to buy more until now. Thankfully, it is an oil that stores well!
Since I bought my stock of Rosewood essential oil, the trees that the oil is derived from, have been severely over-harvested. So much so, it is now on the endangered species list.  It is a tree that is not easily "farmed", so most essential oil is distilled from wild-harvested trees in the Amazon forest.
So now that I am out of Rosewood essential oil, I am faced with the dilemma of how to scent this popular soap going forward. One option is to  use a "rosewood replacer" oil, which is a blend of other essential oils that replicate rosewood as best as possible. Option 2 is to change the essential oil blend using different oils, while trying to stay somewhat true to the original scent. The last option (3) is to scrap the blend entirely, and create something new.
Options 1 and 2 would probably result in a slight price increase, since the essential oil blend would be more costly to produce. Option 3 would allow me to keep the price the same.
