asemetrical thrust is one thing near the inboard section of the
wing... but at the outboard end of a high aspect ratio wing! All I can
say is holly crap hold on for one hell of a ride when one engine shuts
down early.

Is my brain fading or did that huge german transport sailplane in WW2
have a jato fail and the with the yaw created by the one rocket cause
it to take out the glider as well as 2 Junkers tow planes at the same
time?

Its a better world with centerline thrust! Mount two engines above the
fusalage and angle them so the thrust is directed to the side of the
tail feathers. The vector would be small and concentrated at the
center of mass if one engine failed just add rudder.

It might get a pit toasty for the wing runner in self-launch mode, but
how about one at each wing tip?

It seems most gliders these days already have some sort of interchangable
tip, so make a new set with a jet built in.

Fuel storage would be the main issue. If you give up the water
ballast option though, there's plenty of room in the wing.

I would think that mounting a couple of small jets at or just behind
the wing/fuselage junction could also serve to remove some of the low
speed turbulence in that area. Also, if the engine had a tight
cowling around it then perhaps some water could be sprayed or drizzled
onto the outside of the engine and the resulting steam would mix with
the exhaust to provide some additional thrust. SWB Turbines in
Neenah, WI (SWBTurbines.com)has a Mamba turbojet which puts out 11
Lbs. of thrust. It is only 3.5 inches in diameter and would fit
nicely at the wing junction interface. SWB also has 45, 60 and a
100Lb thrust engine.
