Welcome Joe! Re-hydrate with water and send it! My vote anyways. It looks like you are making close to 5 gallons / 20 liters with that grain bill, you might want to use 3 packs for 1.075 gravity, or brew a small beer and use the cake from that! Recommended pitch rate would be close to 250 billion cells. (you get about 80 Billion per 11.5g packet of US-05)
Most people advise against starters with dry yeast, the yeast is packaged with stored nutrients and are best when hydrated in water instead of higher gravity wort. A viability starter likely does not have benefit with dry yeast.
Personally, I have re-pitched cake from dry yeast with great results but did not go past 2 batches with the same yeast. I guess you could call that an extended starter
