I would try to blow those shapes! I know you are not familiar with working with sugar, but you may be able to find some youtubes on the subject. I would blow a bubble with sugar, elongate it, snip a hole in the top of the bubble and gently pull the edges outward and back towards the skinny part, cool it till it sets, and then take it off the pump. This would require lots of practice, and you would need to invest in some equipment such as the pump with the blow piece, ( I purchased mine for approx $26), and a heat lamp, silpat, and a microwave.
If you have the time and money to invest, its totally worth having the skill!
You may also try to pull the shapes, perhaps take a ball of sugar and work it into the shape of a cone, until you get the desired shape?
