That sounds nice. 5MW car engine 🙂 Even if it were just very heavy duty trucks, it would still be great improvement over current ICE fossils. Definite ship powerplant material.

I think the shielding is the major problem to miniaturize, others are more or less just engineering challenges.

If I understood physics right you need something that has high hydrogen concentration to capture neutron radiation which basically means water, that that is something that weights a lot. Tried to find some measurements about capacitors but didn’t find any. 25-50kV doesn’t sound much, but IIRC those capacitors are quite big. That might be another not so minor challenge.
