$200: Contemplating overcall ITM in BB A9o 3-6 w/ 4k vs 12k,3k

[Scotty_12]

BTN 36/20 through 100 3 handed, I have no doubt that I crush his range
SB 37/8 through 85 3 handed

Felt this could be a good chance to get into HU with a good stack. If SB wins stacks become 9k, 7k, and me 3.6K which I am not particularly fond of. Insta call fistpump territory, or do we need a stronger/suited A?
