Multiboxers are by and large pretty serious players and I'd imagine you'd get as much support for the paid version as you have for the free. You may even receive enough income to allow you to focus full time on it. You certainly deserve it for the quality product you've produced and the dedication you've shown over the years.
Blizzard hasn't allowed add-on authors to charge for their add-ons for almost 6 years now. Here's the updated source from that article:

1) Add-ons must be free of charge.
All add-ons must be distributed free of charge. Developers may not create "premium" versions of add-ons with additional for-pay features, charge money to download an add-on, charge for services related to the add-on, or otherwise require some form of monetary compensation to download or access an add-on.
