Aging whisky on grains

[Diverch]

So as I'm yet to build my pot head, 5weeks ago I put some sugar neutral on SD dominoes. I got a trial pack of French and amaerican oak.

I'm very impressed with the results after 4 weeks on wood and 1 week airing. However, they are missing something and I presume it the lack of grains.

My question is, if I through some crushed grains into the mason jars, do you think it will empathy some of the missing flavour? If so what grains? I was thinking dark crystal.

Thanks

Ps I'm already planning my first whisky mash for next week! Advice there would also be welcome.
