I received input mentioning the multicast rate. Since the mcast_rate modification looked straight forward I choose to try it out right away. I did see an improvement in the behavior of our network. By improvement I mean that I see the network routing through adjacent nodes using hops, verified by trace route, and achieved higher throughput values. A value of 36000 was used for the mcast_rate but anything higher broke the system (Not sure why). I used that value since my research indicated that the value was in Kbps and Simon pointed out 36 Mbits.

This should tested before trying to hack the TQ calculation with some own RSSI based submetric. The mcast_rate trick is currently only shown in an old OpenWrt wiki page [1]. Maybe it should also be mentioned in the main OpenWrt configuration page [2]. I will leave this to the interested reader... or I will change it when I have some time to confirm it with a current OpenWrt.
