There's another option, rarely if ever mentioned, perhaps due to the impracticality of revisiting old construction, but there's the possibility of supplying 'unpowered locos' to use as trailer vans (cab cars), save for perhaps HEP supply since cab cars are required to have more mass than the coaches trailing them (some Cabbages were required to have concrete added for mass for more safety in a collision), but rather than using old locos to do this, use the current powered loco design less prime motor and drive motors on bogies, and add power to the unpowered ones later if/when needed....If this were somewhere other than Canada, I would argue for fixed consist with a loco at each end, but since this is a minimalist bare bones fleet strategy anyways, I would argue that VIA should have as few constraints on utilisation as possible. That means the loose car option has to remain, and one big loco on the fromt may be preferable to two smaller locos on each end. Perhaps dual ended locos have their place here - they dont need to be turned, and are still relied on in lots of other places.

Rather than VIA spec'ing this, it could be a bid option made by the manufacturer or vendor putting together a trainset from various suppliers. VIA's concern would be whether the loco manufacturer would still be in business come the time to power the loco shell, but that would be a concern anyway, no matter who and how any supply a bid.
Using the old F-40s would/could certainly be an option, albeit how they'd run at top speed on their old bogie design might be a concern, let alone coupling into a 'drawbar type' trainset unit that would be addressed better with 'like kind' trainset.
The Austrian coaches the Brightlines are based on do have driving trailers as options.

The railjet from Siemens is the new premium train in the high speed fleet at Austrian Federal Railways (ÖBB) and, now, people from the industry and fairgoers will be able to board it for the first time at InnoTrans 2008. At this bi-annual show in Berlin the vendor will present a shortened ÖBB railjet train formation, consisting of three cars and a locomotive.
The standard configuration of the new ÖBB railjet is a seven-car set with a total of 408 seats in five different types of car: a driving trailer with premium class area where the seats can be adjusted to a reclining position; an open-plan car for the first class; a Bistro car; and four open-plan cars in the economy class, one of them with a family area. The Bistro car accommodates the area reserved for wheelchair users, who can access it via lifts at the car entrance doors with the help of the train crew. All cars are fully air-conditioned.
Every railjet is hauled by a Taurus locomotive and is operated in push/pull mode. A rake is 186 meters long and, counting the locomotive, even as much as 205 meters in length. In their current configuration the trains are designed to run at 230 km/h and meet all requirements in international high speed rail traffic. SF400 type bogies are used, which have also been in service for the ICE2 in Germany for years.

Not sure if that's the exact type Siemen's modelled for the North Am market, but it's the same family.
