i notice a lot of the molecules you describe are base notes. They tend to stay close to the skin.
Generally speaking, projection is directly dependent of the weight of the molecules.
Hence, the more top-notes (light weight molecules) and the more alcohol (evaporation), the bigger chances are you will gain in projection.
Secondly, if the top-notes contain light weight molecules with big impact, normally aroma chems, that one would dilute to 0.1% for normal usage, the projection will be greater too.
On the other hand, using *only* light weights, will not give you any base that provides wearability over a few hours, or even minutes. It should be a balancing act between top-heart-base notes, generally speaking 60:25:15. If your composition lacks on silage and projection, pump up to 70:20:10 in the tops, IMHO. Or even 80:15:5, when some heavy weights in middle and base tend to convert your composition to "mud".
For the desired vanilla effect in the room, take a look at TGSC and look for the chemicals with a vanilla scent and have a low molecular weight. Ideally, your composition should contain some 'sweet' molecules in top, heart and base. The beeswax honey and vanilla are definitely base notes.
Take a look at e.g. bezoŽ tincture, benzaldehyde, (ethyl) vanillin(e), linalyl acetate, methyl ionone, levistamel, vertraldehyde, and even de aldehydes like C11 undecyleen.
