What if you used a deep under ground nuclear blast to create a large hollow
or molten area at the point where the plates come together.
Since the plates move so little per year, wouldn't the hollow/magma area
allow for future movement to occur gradually rather than causing the
pressure to accumulate.
I would think that even though almost no mass is actually consumed in the
reaction that sufficient compaction of less dense materials would occur to
create more room for the plates to slide to.

One also has to differentiate between "slip" faults and
"break" faults. Very different and not always clearly
separate. I would suggest that the lubricant approach
would work with slip faults. It would not work with break
faults. In (a) you are dealing with plates slipping past
each other; in (b) you are dealing with plates running into
each other such that the only way around is to snap one
of the plates. Very distinct phenomena.
Suppose you stuffed a hundred tons of dynamite down a borehole in the middle
of a break fault and set it off, would that trigger the earthquake early?
