the two contexts created by app_lua were designed one for loading at 
startup and the other for reloading every time. Reloading on demand at 
runtime is not possible. I thought of checking the timestamp of the 
script, but can be a bit risky if saving on intermediary state during 
updates. The scripts are loaded in each process, sending a mi/rpc 
command will require to do some inter-process signaling. Both doable, 
not in my short term plans, though, if someone is contributing, will be 
appreciated.

Some options for speed up with existing code:
- you can compile the Lua scripts, so reloading it each time will be 
faster (no more compile on-the-fly)
- not sure about this one: in your script loaded at startup you may have 
some logic to load another script based on your rules (e.g., file 
timestamp, periodically, ...)

Cheers,
Daniel
