It's possible, but there are major downsides to a 6 car 319.
Putting aside cost any costs involved and working out diagrams to allow best use, there is an issue with power to weight ratios.
4 car units have 2 powered bogies, both on the PMS (Pantograph Motor Standard). By adding two trailer cars to a 4 car unit, you are adding about 60t to the weight of the unit without increasing the power to move it. This will have a big effect on acceleration and possibly top speed.
4 car 319 has a single motor carriage. So a 6 car is going to need an additional one creating. As the 458/5 project has shown, craving up stock is rarely easy especially on to this level.
