Slightly lowering the saddle will avoid over-extension of the right leg (in OP's case without shims) while left leg will be slightly under-extended. Under-extension results to much less problems (or even none at all) than over-extension - at least according to two pro bike fitters Steve Hogg and Neill Stanbury.
However, I'm not recommending it as long term solution, only up until OP get his shim.

It is quick and easy, and it is how some people deal with leg length differences, and adapting fit to the shorter leg is a far better solution than to the longer leg...but, the OP asked a very specific question that this doesn't answer.
As a reminder:

And I will reiterate, yes. Especially in the context of the specific physical issues the OP needs to ensure are accounted for and addressed in his bike fit. I think it is borderline irresponsible to be telling him to start playing around with his seat height.
