Opposition Class Duna missions?

Opposition class Mars missions involve short stays in the vicinity of Mars and (usually) a venus fly-by on the outbound or returning legs of the journey. They take less time than the conjunction class missions, but require more dV.

Examples of opposition class missions include the

from the novel Voyage. The 2021 inspiration mars fly-by is like an opposition class mission but doesn't involve orbiting mars.

I'm just wondering if anyone has been able to do any sort of Duna missions that involve a fly-by of Eve on the way there or back. One issue I've found is that the planets don't line up as frequently to create the gravity assists.

I like the idea of doing an opposition class mission to Duna in career mode to reduce the time waiting around in Duna orbit and get extra SCIENCE from an Eve fly-by. Plus I want to make an inspiration Mars style mission in the game.

You certainly can do then in ksp the thing is however most haven't add there is no need with time acceleration. In real life you have to deal with transfer Windows and when one is a long time off you stay looking at alternatives to the most optimal, and make trade offs on time and cost (more dv=more fuel means more money)

While in ksp we can just time accelerateand go
