Different archive templates??

Is it possible to have archives that are displayed from a wp_get_archives call to list on a template other than archive.php?

I have my main blog pages, where I have multiple categories of posts. In the sidebar for those pages, I have an Archive listing by Month, Year, and that displays all of my blog postings using the archive.php template.

Now I am creating a sort of mini-blog, separate from the main blog. Just one category of posts. I don’t want these posts intermingled with the main blog’s posts. I have it all worked out – except when I try to create an archive of JUST that category’s posts. Using a plugin, I was able to list the archive for just that category — but when someone clicks on a month, year for that archive, the post is now displayed using my archive.php template. Fine, except that template has a sidebar that shows the posts and archives from the main blog, so that won’t work for me.

Is there a way to insert an archive listing of posts from mini-blog by month, year and have the resulting archive posts display on a different template than archive.php?

Thanks in advance,
KC
