Oh boy something new to try in KSP. Funny I've never seen anyone do this, maybe the imperfect simulation means its never more efficient (in-game).

The transfer times are a killer.

It's only more efficient when the ratio in orbits is around 12 or higher, and then you have to go even higher than that to get more efficient, and takes at least twice as long to complete the transfer.

I'm not sure there's even such a ratio in KSP, even Moho to Jool is less than that.

So you'd need to be in a very artificial scenario for it to be more efficient, and the extra time would be tedious (even at full warp) compared to a regular transfer.

I’m pretty sure it’s done whenever there are inclination changes. Mechjeb had an option for it IIRC.

[radonek]

Absolutely. I've hardly ever done bieliptic transfer in KSP, but I stick to bieliptic plane changes for almost every big inclination change. Δv savings can be huge.

It should work in ksp. Its still an impulsive maneuver.
