Doesn't sound feasible. Keyboard and application are different
processes and keyboard is able to only request text actions.
QInputMethod, which the text component receives, doesn't have support
for changing font except some formatting options for preedit (= active,
underlined word).

(Or ok, you could create a custom input context plugin with special ipc
for this, have that loaded into qt apps instead of current one and
there mess with font property of focused QObject. Not recommending
going that far :))
