Extending an existing custom language plugin

hello there in this part of the forum.

I am currently developing a plugin, which is on it's own just an extension of the Lua plugin. To be more explicit, i am developing a plugin for a more complete integration of Corona and some OO-approaches. 

Well, I know, i have the <depends> tag in my plugin.xml which provides all the sources that i need. So far, so good. 

My problem right now is, that all my extension points are seem to be ignored. I try to explain everything that i tried, need and have done in a short few bullet points below:

• i tried to add my extensions (for example an Annotator) with something like this:
  <annotator language="Lua" implementationClass="path.to.my.CoronaAnnotator"/>
  this Language is not my own, that one is from the existing Lua-Plugin (props to sylvanaar for this). My guess is, that only one language-key can be existing in the "extension-point-pipeline"
• i tried adding my own Corona-Language file, but they need to have the same file extensions like in the Lua-Plugin, since Corona scripts are nothing more than Lua scripts.
• I tried to take the same language and tried to solve this by ordering it. This is not possible too
• I want to keep this plugin as its own project, because i think it is the more cleaner approach (programmatic wise)
  Basically I would like to get those two plugins up and running parallelly. So that, where my plugin fails to deliver, the other one kicks in and takes over the job. 

I don't know right now if i am missing some steps in my searching-/trying-/raging-/finding-process.

Any ideas here?

Thanks and greetings, Felix
