I actually did that for more than 3 years.
I started* the game in my Cobra Mk III "The Dancing Groigan" and have been flying it mostly** exclusively from Gamma in 2014 until October 2017 (When I bought an Anaconda).
* "Independent Trader" tier at the Kickstarter: something sounded right to me about starting the game in Lave with a Cobra and only 100 credits.
I did almost the same. Picked the "Pirate" option in the Kickstarter because I wanted the nostalgic start option (but didn't want to pay the extra for Independent Trader), and stuck with my Cobra until I wanted more cargo space for trading (so not very long).
I kept the Cobra though, but haven't flown it for years...
