c:5 won't work; c:5 gives a C major triad.

I don't know how hard it would be to define a new modifier :five.  I would
not be in favor of accepting such a modifier into the main code base.

The proper modifier for creating it in LilyPond is c:5^3 (which is actually
shorter to type than c:five).  One can also use c^3, which is even shorter,
but it has the implied 5 and so may not communicate well in the source code.

It requires a simple chord exception.

This has been nicely discussed here (the rock term for what you call a
"quint-chord" is "power chord"):
