Just don't wear your pack into the airport or you might be repeatedly shot in the face. It's not worth saving the weight, even if you CAN pack all your clothes into your pods!
Something to look into would be sports equipment allowances, I haven't personally researched this for paintball, so I don't know if it 'counts'. . . but
Many North American airlines allow sports equipment to travel as free baggage as long as it meets requirements and is 'pre registered'.
I know several people who have traveled with large amounts of scuba gear under this allowance . . .
best bet is to put all your clothing in your hand luggage - clothing being casual clothing. Then your sorted! saved us money on the way back from Paris.
