But the kind of skeletal support structure for it may make it a good chunk heavier. But even moderate improvements on performance could make it for an interesting purely electrical air craft.
Edit: Upon further reading, the Biefeld–Brown effect which ionocraft exploit depends on High voltage DC which unless I'm mistake Polywells have in spades. yes?

A 100 megawatt reactor just to lift 50 metric tons? Applicable only in the atmosphere, where we have various other options for achieving lift? Why would someone want to do this?

All small scale ionocraft are completely noiseless, I haven't seen video of any bigger than prox 10 cm across though. I'm thinking of building one with my EE friends.

Pure speculation, but has the concept any application to levitation in sea water? Certainly the work needed to lift or balance a heavier than water submarine is much less than doing the same thing in air. And, there are certainly plenty of ions aviable. The problem might be too many ions- shorting out the system. If it worked, it presumeably would be much more stealthy than flooding or pumping out ballest tanks or possibly using fins. If the force was directed forwards it would again presumably be much quieter than a propeller. Is this anything like the silent drive popularized in the movie "Red October"? [Edit] Actually it is MHD, perhaps similar in princible?
