Good school exercise...
Very fine example, and useful too.

Would it be feasible/desirable for a future version of Lua to use PEG
techniques (coded in C) in its own parser? If LPEG was distributed as a
standard library, then would it be possible for Lua's parser to be written
in Lua, perhaps with a few extra library functions)?

Same reaction as Peter, what for? The current lexer will be probably always faster than an LPeg implementation (as it is hand-written), and is able to handle subtle corner cases of syntax... On the other hand, I suppose it would delight people wanting to customize Lua syntax... :-)
One can rewrite at least luac this way (direct bytecode generation).
