HI
First of all, I'm not very experienced in developing software for embedded linux devices.

OpenWRT is running on the Linksys WAG160N and the WAG320N is also a Broadcom BCM6358 device.

So, what is missing to get OpenWRT running on the WAG320N?

After reading a little bit about OpenWRT on devices with ADSL-modem I found out that the main problem is the missing PPP/ADSL driver - Is this correct?

The WAG320N is a Linux powered device and due to a bug in the web interface of the default firmware it is possible to access the shell.

During boot the WAG320N loads several Broadcom drivers (Ethernet, WLAN), the USB interface driver, and the "PPP generic driver version 2.4.2"

Would it be possible to install OpenWRT on the WAG320N or are there other problem which I haven't thought of?

the forum search shows that there might be some troubles: https://forum.openwrt.org/viewtopic.php?pid=102924
Another attempt is to read a bit through the wiki on how to get new devices supported and then diff the sources of the wag160n (for example this one) against the wag320n sources (you probably have to ask linksys to publish them) to find the differences between those two devices.

The discussion might have continued from here.
