There are plates that allow an SPD-L shoe to mount SPD cleats
However I don't know of one the other way round.
It may be worth inquiring about the Shimano Sm-SH85 SPD-SL / SPD adaptor
These are designed to fit the plate using the three hole fitting and then the SPD cleat to the plate.
I do not know if you can fit the cleat to the three holes and use the two holes of he SPD fitting to attach the plate to the shoe
