just fork and change whatever you need and build it. that's the magic of open source. if someday your own personal fork gets enough attention and the use case you implemented is solid enough, it'll pick up steam and will possibly get merged (or not) into upstream. but still, you are free to change and peruse whatever you see fit. you got a lot of work done for yourself for no effort at all. time to put in your own.
