Would there be issues with decelerating?

No more than there would be with accelerating, I suspect. "Decelerating" in space is just accelerating in the opposite direction.

Which makes the prospect of engines failing halfway through a lot more scary.

Lithobreaking is always an option.

Put it on a lazy Susan, run it for the 2nd half of the trip. (But the paper describes the mechanism for deceleration without repositioning the engine)

With some duck pancakes?

Yea maybe this thing works like a microwave as a biproduct, keep em warm.

I imagine ducks and rabbits would be the best spacestock.
