yes, batman-adv on 5 GHz works for us.

There are regulatory limitations for the higher 5GHz channels, but channel 
36-48 should have no restrictions for ad-hoc use - if your chip/driver 
supports it.

I would suggest to first look into getting Ad-Hoc mode working without batman-
adv before continuing any further. You might need other sticks, but there are 
definitely USB chips out there supporting Ad-Hoc (you may want to check out 
ath9k_htc based ones).

Cheers,
