SurfaceLights runs without an issue. Karbonite 4.2 is the .25 compatible release, but it includes a version of Firespitter that shows an incompatible warning on load.

MechJeb won't calculate a transfer to a planet unless you're already in the SOI of Kerbol. It's fairly decent at flying the maneuver node created by other means. I've had issues from LKO though using low thrust ships--the initial ejection burn from LKO took so long that the trajectory wasn't right by the end and the deltaV requirements to complete the maneuver skyrocketed.

I had to test a KFR x2 booster splashed down. That was a fun one. I had to build a booster with low fuel, put the booster I wanted to test on top of that upside down and empty, and put about twenty chutes on it plus a retro burn to keep it from blowing up when it hit the water. Fun times.

Why not just switch back to the Space Center after you've reached LKO and fast forward to the window from there?
