Acetone will mix with your limonene, so youll have a mix of limonene, acetone and alkaloids, then what? Dont do that

Instead, you have to salt out your alkaloids from limonene, either with vinegar (or another acqueous acidic solution) or with FASI precipitation, check BLAB for more instructions..
I am not aware of any other "clever" way to get the alkaloids faster out of limo and into a freebase form ready to smoke...
