activeCollab new module development question

I am wondering if anybody have developed activeCollab module. I am getting a problem with a module that I am developing it. The problem is that this module needs to change on instalation some default creativeCollab view files.

For instance, our company has developed a module which adds new date field to ticket view and class.

So in order to user install this module, some files are modified and not just added. Which is not a very good way because a code conflict can happen.

Which do you think is the best way to achive this?

cheers!
