it possible to carry P3E? numerous test launch use dummy mass why not
launching one bigger satellite instead

If only, I suspect there may be issues with the fact that P3E carries a motor and explosive fuel. CubeSat's are passive and sealed inside the deployment Pod, they present no safety risk to a launch.
I'm sure every single AMSAT-NA Board member would love to see a linear transponder satellite in HEO. It all comes back to money, $10 million is needed to launch P3E and further $10 million would be needed for it's replacement 10 years later to ensure continuity of service. However, in the years to come another approach may be feasible - a 3U CubeSat with deployable solar panels, antennas and an ion motor, but it will take many years and several launches to develop and test the new technologies required to achieve that.
Raising $10 million is probably beyond what can be done on Kickstarter, only one project which had mass appeal has ever raised that kind of funding. Getting up to $250,000 on Kickstarter may just about be feasible, enough for a 3U CubeSat in a low 700 km orbit, but I'd suggest larger amounts are out of the question.
Meanwhile, let's hope some opportunities arise to fly amateur transponder packages on commercial or research satellites going to MEO or GEO.
