Hi!
The best way to see if this will work is to try it. You don't mention model year but I don't see any with significant overlap; generally you would want all seatbelt installs to maximize space, and alternating seats so the baby is in the center may work best. Once they are all properly installed, you need to check for independent installs. That is, remove the center seat, check that the outboard seats are not moving more than 1". Mark the belts with tape or colored chalk to see where they should be. Reinstall the center seat. Remove the outboard seats, check that the center is still moving less than 1". Reinstall the outboard seats to the marked line.
