Hi,abeonis,
I'm not sure my ePub Maker & Mobi Maker can do your work, it's designed for Word to ePub/Mobi, for professional epublishing solution.
This tool has been release for three years, and sold very well, but strangely, nobody knows it in this forum.
If you would like to try the beta version of 2.0, I can send you complimentary license.
Please vist
