That was a good idea but I ended up doing it different
I removed OEM speaker and housing. I ripped the speaker apart and cut the plastic ribs from the housing. I also had to remove the foam around the face of speaker for reusing.

I installed new speaker into housing and soldered new wires into housing adapter. These go to new cross over mounted inside door panel

After sound proofing door and inside door panel, I mounted crossover inside door panel along with new tweeter.

The OEM plug connects to OEM housing and everything works great!!
