Request to co-maintain Commerce Beanstream module

Several months back we began work on a Beanstream integration module for Drupal Commerce, and somehow missed the existence of this project in our initial survey until quite recently. Had we realized sooner, I would have submitted patches to this project directly, but instead have built out much of the functionality on its own in a GitHub repository (https://github.com/rnao/commerce_beanstream), covering a couple use-cases this module doesn't (card on file, void transactions), and ignoring at least one other that this one does (capture-only).

While much of the original logic overlaps, I don't currently see an easy way to offer a patch to this module's 1.x-dev branch to merge in the extra features. As such, I'd like to offer to share maintainership of this module and import our github repository as a 2.x branch. We could subsequently merge in the Capture functionality, and any other niceties (error-handling might be better on the 1.x branch, not sure) to generally improve the whole thing. Does this sound workable, or is there some other way I can contribute our efforts back to this project so as to be generally useful?

Here's the GitHub repo: https://github.com/rnao/commerce_beanstream

Thanks,
Derek
