Very novel! This is an idea that I like a lot - I expect that some criticisms of Transport missions is that you'd feel like a glorified bus driver, so this is a deft way to get past that with some real drama.
To be honest, I like the idea of a "glorified bus driver" in space! Given we have passengers we can interact with, this could very well be a very entertaining and interesting profession to pursue in ED without being a fearsome bounty hunter or filthy rich trader.
More than a decade ago, I played an obscure game on my Sega Dreamcast, called "Tokyo Bus Guide". The game was never released outside Japan so I had to play the import version. It mainly centers about following all the rigid rules of driving a bus through downtown Tokyo. You lose points for many things - exceeding speed limits, changing lanes or turning without flashing your "blinker" (is that the right English term?), being late at or early on individual bus stops, hitting other cars or forgetting to close the door before departing from a bus stop.
One very funny aspect where the passengers that would sometimes trigger cut-scenes with hilarious dialogs and stories (see the 19:10 minute mark in the video below). Collecting all those different small conversation videos was a main motivation to keep playing the game long after finishing each route multiple times. Now, I understand that this kind of spoken stories will probably difficult to do for a game with the scope of ED, but something in the same direction, for example just text based interaction with the passengers, would already be great.

It's kind of obscure and many people might think it looks dull, but I liked it a lot and it's much more exciting to keep an eye out for all those things you can do wrong than the initial impression might make you think.
I am sure there are other Commanders who would welcome an alternative, less fighting oriented game play mechanic, too.
Edit: also: dat music! Pure awesomesauce!
Edit 2: the Orca boost "bling" sound would also go very well with this "bus driving" kind of game play
