The problem with adj swap is that any alg for it is going to be at least 9 moves. It's very difficult to break that down into intuitive sub-steps.
The method I suggested makes half of the moves (the final 5) completely intuitive and difficult to mess up, because the cube is reduced to the R2, U group. As long as they don't let go of bottom-left two cubies, it should be a doddle.
The hardest part is the first 5 moves, setting up for the re-grip. It requires the solver to remember:
* Bring DR pair up to UB
* Break it up
* Do the R2 swap
* Regrip
... I can't really think of a nicer way to do it. Perhaps some kind memory trick would help. ... like an acronym for the steps. All I could think of is: BASS (Back, And Split then Swap).
