You're right, the potential is there for a 3U CubeSat that can achieve an apogee > 1400 km.
We'd need 1U of that to house the linear transponder but as you say the rest could be used for the propulsion system.
As yet, as far as I'm aware, no-one has actually demonstrated a working propulsion mechanism that can fit in 2U but I'm convinced this is possible.
The launch costs for a 3U CubeSat into 700 km LEO are well within the reach of the Amateur community, our challenge is to develop a means of raising the apogee.
