I'm very sure this would cause problems;
Although this is awesome and a huge amazement,
I think it's likely that it would screw up clients to the server because if I'm correct,
This thing creates new .dts based on bricks and then fixes that onto a vehicle
And a client would not be able to compute that not having the newly added shape.
It'd be like being in a server without downloading add-ons on the server that you don't have.
Not really. The add-on probably has one/a few preexisting dts shapes, and it just spawns a bunch of them, all properly scaled and rotated.
The hacky part would be how the shapes are kept in place.
