Lager with funky bottle refermentation

[Tofek]

Hi guys,
I was wondering what interesting touch I could bring to "simple" lagers and thought about refermentation in bottle by some kind of funky Brett savage yeast, mixed with a classic cerevisiae. Something like Orval : hoppy during first months, but funky 6 months after bottle conditioning.
Anyone tried this ? What yeast should I use for this purpose ?

Thanks in advance
