Odd/fun project question.

a little background first.
I almost exclusively make wild ales. With wood barrels and bottle condition and all the stuff that comes along with making wild ales.

I have an empty barrel that I have been looking to fill. I very shortly will have the opportunity to get enough out of date commercial craft beer to fill said barrel. It’s going to be a mix of Pilsner and ipa and other fairly low alcohol, low hops type of beers.
So my question is has anyone ever made wild ale/ Brett beer from beer from packaged commercial beer? In my head I think it may work.
Most beer that type still has some residual sugar left in it for the yeast to eat.
My house yeast culture is probably going on about it’s 200th generation at this point, so it chews through pretty much any sugar and gets wort down to 1.00 fairly easily. so I’m confident it will ferment the beer the rest of the way. Should I add some honey to kick start everything? Or will that just add more alcohol that I honestly don’t really want? Should I add anything else to help the situation?
As the title states it would be just a fun project to see if it works. If not I can dump it without any remorse since it will be almost zero dollars down the drain. Thoughts?

 

Just to make a good drinking/blending beer. I guess I was just looking for any ideas that I may not have thought about. I’m am more than likely going to do it regardless. Also was curious if anyone had any anecdotal tips from doing something like this.

 

im not real concerned about oxidizing they beer as it will sit in a wood barrel for probably atleast a year. From what I have found is Brett tends to eat up many oxidation tasting notes.
