I’ve done similar stuff with fresh evergreen cones, pack em in a jar, fill all the gaps in with sugar, wait for the sugar to suck water out of the cones and produce a syrup. No need to set it in the sun either.
Goes great on pancakes, would probably be a fun addition to a beer as well.
The ultimate extraction would likely be achieved with high proof alcohol. Sugar syrup I think would be less effective than with dry sugar as the dry sugar would exert more osmotic pressure on the tips to draw liquid (and thus flavor) out of the tips.
You can also add them to the boil as you would hops.
