Maybe just put the round ports on the top? If you're building to the same dimensions as the flat-pack, I'd think you'd have plenty of depth for them to run vertically behind the top midrange driver.
As to re-calculating the port size, just use WinISD... you don't need any driver info since box tune is purely a function of volume and port dimensions. Using the flat-packs internal dimensions and estimating a tune around 40hz (2x2" round ports at 6" long), I came up with a 9.5" x .66" slot port at ~5.4" long. Looking at the baffle, which I'm fairly certain is outset, I'm not sure you'd have enough height to work with... maybe just enough if you used 1/2" mdf for the top half of the port. You'll just need to dry-fit and measure when the baffle/drivers arrive to see.
