Yes, Julius uses acoustic models created by using the HTK Toolkit, and
hence other language models that have been created using the same can
also be used with Julius. I have tested it with the acoustic models
and the speech corpus that are made available by Voxforge. The
efficiency is not very high as of now, but its more of a acoustic
model problem that arises due to limited speech corpus rather than the
engine itself. It might also be because I speak 'Indian' English. I am
recording my own corpus by asking children to speak. I am confident
we'll get better results as we keep recording more and more data.

True. I am very positive about achieving very high efficiency in this.

Sure, I'll put up a proposal on the wiki. Thanks a lot for your
encouragement. I'm praying the project gets selected too.
