Sounds like I should just scrap that idea. I do think I'll toss the Graverhopke in though, I like the Brett character from it
I would disagree with calder, stepping up will swing it in the other direction given time
The bacteria in JP are generally very strong and healthy, if you make a small starter and give it a week or so it will be quite acidic, adding more sweet wort will only make it become ever so more sour (bacteria grow faster than yeast), at a certain point the sacch cannot handle the acidity, the souring bacteria will even go so far as killing themselves with acid.
I would grow up a starter and let it sit for ~1wk, taste if its really sour I would add some fresh wort and some baking soda (helps balance the acid)
One last thing I would suggest would be to keep the dregs of JP and gaverhopke separate, you never know if a bottle is gonna make something you dont particularly like so its best to keep things separate until they build up their population a bit, this way you can taste the starter and get a feel for the direction its heading
