I haven't seen anything about reactionless thrust that sounds legit, so I would say yes. Even if the EM drive or other propulsion systems are made they still have an energy requirement and very low output, so a fusion or antimatter drive is a better option.
Steal from Star Trek and cram on a large, or a couple large, bussard collectors. Not sure how you would add them without conflicting with the rest of the design.
I was sketching out some rough ideas on Antimatter reactors, storage, and collection parts for the SE ships, I didn't get very far though.
Could do it with 2 thin toroidal rings, maybe give them the look of copper, wrapped around the front and one near the back. Have them sorta pressed into the hull to add a bit of detail.
I am of the differing opinion here. While there's plenty of reason to be skeptical. no-one seems to have dis-prooven it yet sooooo...
Much of the realism aspect I'm basing on what I've learned from the Kerbal Space Program Interstallar mod that has done the math for most of these far fetched (but plauable) systems. I'm probably looking at a 25-50GW reactor of some kind, primarily since it's enough to power a warp drive. It also provides enough ooph to make electric thrusters not useless. Alternatively, despite substantially lower thrust i was thinking of possibly a VASIMR system since it can be fueled with virtually anything that could be collected in-situ, perhaps from a gas giant.
I may put them on the rear and tie them into the engine/ reactor assembly. I originally wanted to put them on the front to look a bit more like classic trek, but that seems increasingly impractical.
It would be cool to see any pics.
I was going to take inspiration from a BBC sci-fi docudrama thing I watched a while back that used a similar system, for a trip around our solar system. I can't remember the name offhand. Last time i looked for pics of a artificial magnetic field generator i had less than great luck. That's similar to what i remember though.
