There are only two ways I know of to bundle two internet connections into a
single connection in a way that won't cause problems. One is to tunnel to a
remote server from both connections and have the remote server act as a
single originator IP address for all traffic. The other is that a client
gets assigned to a single internet connection when they get a DHCP lease
and then only use that connection until they disconnect from the network.
Switching source-IP mid-session will confuse many pieces of software.
