I'm not sure what DLL file you mean exactly (there are multiple ones), but it's not really a good idea.
It's not possible for us to use the translated files directly; extracting the translation (into a usable form) should be possible, but would require some effort and might not be 100%.
If you send me what you have finished so far (and if you are interested, of course), I can try to load it into our translation program and send you the "usual" translation project with further instructions (on how to use the translation tool).
