The spider drive is completely new and can't be retrofitted or used as a modification. It also can't be used simultaneously with an impeller-ringed hull because the physics are incompatible.
But from a practical matter, it's unlikely that any
existing ships (other than military cargo ships like missile colliers with large open spaces anyway) will be retrofitted to take streak drives. The hyper drive has to be pretty close to the center of the ship for its field to efficiently cover everything, so there's bound to be a lot you'd have to cut through just to get to it, then you have to move a lot of other things to make room for the larger drive.
However, if you have a general idea of how big a streak drive needs to be, you could start building ships now with deliberately over-sized hyper drive spaces, expecting to put a streak drive in later, but before everything is completely built around the drives.
If you're careful about it, you might even be able to design, say, SD(P)s and CLACs with the hyper drive located a few decks above the boat bays, with the space between the hyper drive and the boat bays expected to be removed to let you swap them out. All the power connections etc. to the intervening space would have to be carefully laid out so that they can be disconnected and reconnected easily. Maybe the removable space is configured as one or more modules to make the swap easier to accomplish.
That's something for Shannon, Sonja, and Simões to work on at Bolthole. They'll have to figure out if it's feasible.
