That should work fine.  It is actually quite equivalent to what the
other David's code does.  If you use

\void \displayLilyMusic \rinforza

and/or

\void \displayMusic \rinforza

afterwards, you should see about the same for either version.  When used
in actual music rather than in an assignment to rinforza, you'll need to
write

-\tweak ...

to inform LilyPond in advance that this is supposed to end up being an
articulation rather than standalone music.  It will be able to figure
this out when just writing \rinforza, but if you write \tweak ... in the
music itself, the parser needs the leading - to interpret this
correctly.  And it will be at least several weeks before I manage to
teach it to be smarter than that.
