Crazy idea for flat corked beer

[millsbrew]

I bottled a Flanders red after 14 months and proceeded to cork it. I tossed in some Brett to help carbonate the beer. But after a month, still nothing on the carb front. Going to try warming them up on a heat mat, but I was thinking of a crazy idea to help it. What about adding more liquid yeast and sugar with a needle through the cork (assuming I can find a doctor friend to get me one)? Anyone ever try this? I won’t be uncorking all these and repitching. So it’s either needle the cork or drink it flat.

Thanks in advance.
