The planes I had in mind were manufactured with asymetrical and opposite seating configurations. My concern was whether or not Douglas built them with the tracks installed at different BL locations.

True to a certain degree. Removing the intercostals or other structure that support existing seat tracks would be prohibitively expensive without the OEM's direct support, but adding additional seat track is done all the time.

16G for forward loads on new design.
The other directions are as follows:
3G up
4G side
6G down
1.5G rearward
