Hello, what fun to be had with this. The only oil I have that smells like coconut is Wild Massoia from Oshadhi, and that smells like green coconut to me. It is certainly pretty pungent. From what I can gather elsewhere, coconut is not a strong smell. I use Fractionated coconut as a base, precisely because it has no smell at all.
If you wanted to make your smell stronger using the method you are already using, then I may suggest you tincture it for longer and then let it evaporate a little to condense it. For flowers, the tincture medium would be recharged many more times.
Look up enfleurage and tincturing and see what you find. I would imagine dried coconut would tincture very well in oil as it is very fatty sort of flesh. Please keep us informed on how you get on. I may try some myself too.
