If I understand correctly, what you're saying is technically possible, but it'd be rediculously hard and complex. Not to mention the rotating mechanism probably can't handle the weight of 8 at2k airtanks and the vinyle tubing.
Also, read Thirst's semi-auto 2k thread(link on first page) before you post in here. They discussed using two triggers, one to open the 2k valve, and another to pressurize the airtank.
How are you getting a constant stream of air? How are you getting multiple shots out of one at2k tank? How retarded do you think we are? Pictures would be helpful.
