You firstly have to modify your breach to receive the funny shaped rounds, that just takes a dremel.
The real problem is aligning the rounds coming into the breach. For that you need either to build an alignment system out of the hopper, which would be large and prone to jams. Or convert your marker to magazine fed. Tippmann just released a modification to make the 98 magazine fed although it's out the top magazine. I believe tacamo made a magazine conversion kit as well.
