you can go to 2 8" aeros or a single 10" aero if you want to, but as far as port volume goes ( as several others have already posted) 2 - 6" aeros in a daily application should work very well and keep your port length fairly reasonable, with aeroports (with both flares used) for daily applications you only need about half the port volume of a standard slot port or a non flared round port, with 2 x 6" aeros you will be at 56.52sqin that would be the equivalent to 113sqin with a slot or non flared port , with 2 x 8" aeroports you would have 100.48 sqin, that would basically be the equivalent of 200 sqin of port volume in a straight slot ported enclosure.
With the subwoofers and box you are using I would probably go with the single 10" aeroport( 78.5 sqin / 157 slot port ) if you are going to change it, this would give you more port volume than the 2x 6" aeros and less length to acheive the same tuning as the 2 x 8" aeros.
