Suggestions for partigyle brew with Denny's BVIP

Im just getting ready to start a boil for a 10 gallon batch of Denny’s BVIP and got to thinking " that’s a lot of spent grains to waste".

any suggestions for a 5 gallon Partigyle brew?

I have some smoked malt and was thinking a smoked porter might be nice.

Any grain additions I would want to make besides the smoked malt and how much smoke malt would I want to add?
I’ve read it does not take much smoked malt to overpower the beer. What would be the right amount of smoked malt if I go that way?

Heres the grain bill. I was a little short on the munich
