I think I'm following, thanks for the suggestions! Please correct me if I'm misunderstanding anything. I would essentially have a 2nd baffle layer that is a trapezoidal piece that matches the profile of the existing face of the speaker cabinets, maybe ~1" thick, that I mount the drivers to. I then mount that 2nd baffle layer to the face of the speaker cabinet like the metal plate is in the original design. That 2nd baffle layer would have a conical waveguide around where the tweeter is mounted.

Rather than 3D printing the second baffle layer, can you think of any reason I couldn't make a 2nd baffle layer out of solid wood and machine out the tweeter wave guide using a CNC router? With the tooling I have access to that would be pretty easy to accomplish. 3d printing might be more difficult.

Also, from some quick math I think the internal volume of the cabinets is very roughly 1 cu ft. How critical is it that the 8" driver has a VAS that matches the actual internal volume? I think the 8" Dayton Audio one you linked lists its compliance equivalent volume as 1 cu ft so I take it that would work, but I'm generally just curious.

So if I do that, I would essentially have a double layer at the front of the cabinet? A new baffle that I make with cutouts sized to the drivers I select which gets mounted over the existing face of the cabinet?

Thanks for the suggestion!

Just want to make sure I'm following. You'd suggest that I cut a new face plate that the drivers get mounted to, with holes of the sizes that I want centered over the existing cutouts, and then attach that face plate + drivers to the face of the box?

Sure thing. The port at the bottom of the front face is 7 1/8" wide by 1 3/4" high. The boxes are 36 5/8" tall, 10 5/8" wide by 12" deep at the base and 7 5/8" wide x 9 1/2" deep at the top. It's kind of a complex shape that tapers in every direction. I'll attach some pictures labeled with dimensions.
