Lua? Whoa!   Thats a super-heavy-duty scrub :-)
Anyhow if thats the chosen route, a path could be with an interim dual-
language period -- as follows:

1. Add lua sources into emacs -- relatively trivial
2. Build data-structure bridges for communicating data structures
between elisp and lua
3. Code up something like python's 2to3
for translating most of elisp to lua
[Note: most is doable, all is not]

Such bridges already exist -- eg pymacs, eclim and emacs-eclim.

Anyhow -- dunno if this -- elisp-obsolescence -- is the main/real
