Can I substitute bridge in place of mesh?

Is it possible to get the same functionality you’d expect from mesh with mme from a ptmp bridge? I want to be able to set up a random node anywhere in range of the others and have it become part of the overall network without additional configuration each time I bring a new node up. I also want to be able to bring all nodes down then bring them back up in a random order. All nodes will use omni antenna and be within a 100 or so yards of one another. I really need it to function as a multi-point bridge with no designated master node. If I bring up unit 2 then 5 then 8 then 6 then 3 in that order then I need them to see each other and link up without additional on site configuration. Each node will have cellular back haul available but on occasion only 1 unit will have internet connectivity to a satellite when cellular is not available. I need the nodes in the bridge to be able to share back haul resources as well. If node 8 is utilizing 100% of its cellular back haul I need it to pull back haul from other nodes not using 100% of there back haul. Also this system will not be a always on system it will be set up, used, then taken down moved and setup in random order multiple times so there will never be a designated “main” node. I want this to function as a mesh style topology but without the limitations of mikrotiks mostly abandoned Mesh and MME. I want the nodes to form individual bridges with all other nodes in range and be able to share back haul resources. Is this even possible to use bridges to create a mesh style wlan network with multiple egress points to the internet that can be shared?
I am not expecting an explanation of how to make this work only looking for an answer to if this setup is even possible at all.

All thoughts,criticisms, and advice are all equally welcomed.
