Aggregate TWO wireless links (with routing?)

Good morning.

We have 2 physically separated networks
network A: 192.168.19.0/24
network B: 192.168.5.0/24

We need create a link between the networks with the maximum speed.

We have already created 2 MIMO 5GHz wireless bridge links, with 711A-5Hn-MMCX devices.

Now 711A-5Hn-MMCX have IP addresses within 10.0.0.0/24 subnet.
device #2 is conneted to RB493G ether7
device #1 is conneted to RB450G ether4
device #4 is conneted to RB493G ether8
device #3 is conneted to RB450G ether5

What’s the best configuration for RB493G and RB450G routers to achieve wireless link aggragation?
Interface Bonding? VLANs?

I also need to preserve the possibility to configure 711A-5Hn-MMCX devices in future from 192.168.19.0/24.

Sorry if wrong forum category

TIA
