Sure, install headers with flange,add short, flanged tube to each new cat and a flange on the cat-back exhaust. Then, make another flanged set of pipes only to bolt in place of the cats when not using them. You can do the same thing with slip fits & clamps, one end or both ends, but won't be bolt-in/out.

If you haven't been down to Corey Henderson's shop, Henderson Performance Technology in New Braunfels, might be a good time to go. Call & make an appointment and you may be able to wait or spend the night, while he installs the headers, fabs the cat sections and tunes the engine for the changes. Corey makes LT5 headers in his shop!
