Low wines into a thumper keg

[Notstupid]

I accidentally made a 12 gallon rum mash for a 13 gallon boiler without thinking about the headspace, so I decided to split it up into two batches. And I was thinking, I'm making a thumper for my still, so how would it sound if I were to strip half the mash without the thumper keg, then distill the other half with the thump keg attatched, and putting the low wines in it? I usually like my liquor to have a strong flavor, so I thought it might be a better idea than doing a strip and spirit run for the entire run.

As a side note, my thump keg is a repurposed container for pickles, anyone know the best way to get the smell out of it? I don't want my friends to be off put by the smell or taste of dill.
