It is not "more traffic on wifi". If your 3G is metered and you are connected to wifi, _all_ traffic should be on wifi.

The protocol allows to not use 3G for data-traffic with the "backup-flag" (MP_PRIO-option in RFC 6824).
Or, it is also possible to simply not open up a subflow across 3G and only create it after the phone lost the WiFi connection. MPTCP supports break-before-make scenarios.
It is simply a question of instructing the kernel to do one or the other through some kind of configuration interface (may it be sockopts, sysctl,...)

Just FYI: my home Wifi is routed to... a 3G, metered connection.
Far from ideal, but less and less unusual:
