I ran into this issue with my own setting, which seems fairly similar to yours. My solution was to create a variant fusion torch with 0.2g per system and 1.5 mps delta-V per tank of water. This is the same basic performance as the fusion rocket (acceleration * ISP = a constant, in this case 0.3 at TL10, vs. 7.5 for the torch as written). It's still limited superscience, due to the temperatures involved, but makes for a more interesting set of tradeoffs.
