I meant that more in terms of operating and management efficiencies, not so much about the network -- there are a limited number of options for improving the latter, but more frequent service along Plains into downtown Hamilton and along Beach/Lakeshore into downtown Burlington would be a good start. Perhaps some transit connections between Burlington and Waterdown as well.
There would probably be a fear in Burlington that the needs of the larger portion of the system in Hamilton will take precedence. But it doesn't have to be that way, and it may make Burlington's transit spending go farther if some of the unit operating costs are lower.
I'm surprised Halton hasn't brought transit for its cities under the regional umbrella as well. Though the local services seem more oriented to supporting GO service, and the urban areas are fairly disconnected aside from Burlington and Oakville. The best option for combining systems would depend on travel patterns between the cities -- is there more of that between Burlington and Oakville, or Hamilton and Burlington? It's hard to say given that it's still relatively easy to drive between all three (and the generally poor service in the industrial/business parks along the QEW is a hindrance to encouraging people to take the bus from neighbouring cities, though I believe BT has upped its game... hard to do when they're so large and spread out though)
When the Dundas BRT is built, local transit routing/scheduling in the area should be revisited.
