Hey Roy - currently you can't do this. We have an old template system and it is not as flexible as I want. (developed first for joomla 1.0 and it was great back then...)
Now with that said - ccomment5 will follow the joomla conventions in 2011 and we will go really closely to what joomla has. I'll also add few module positions so that you could directly load the module in the comments.
The next question on your part is most probably: "when is the new version coming out?" Answer as usual: "when it is ready" but if you want to help soon we will have a beta
Cheers,
Daniel
