Sure, seems reasonable. I’d rather have a shield booster than a heat sink, never felt the need for one TBH. Also, I’d recommend you drop one of the econo-cabins for a small cargo bay, because some passenger missions award 4 units of Nanobreakers etc.
You’re only set up for bulk passenger missions with all Economy class. I don’t think you can split a party across multiple cabins. You can put multiple groups of Economy passengers in one large economy cabin, if they fit.
So I wonder whether you will be able to ever fully load yourself and take advantage of all those small cabins. And even if you do, unlikely they all want to go to the same destination, and it could be a hassle flying all over the place (unless you plan to find one of those special systems in the far reaches of the Bubble – which sound boring to me because you only go back and forth between the same two points, grindy grind).
Personally, I’d trade two of the small cabins for cargo space, so you can run the occasional light hauling mission alongside passengers.
Bulk passenger missions are always the same. Shuttle a party to a destination and you’re done. (Occasionally, they might have someone after them.)
I’d trade one of the larger economy cabins for business class or first class. That opens you up for VIP passengers, which will offer you a lot more variety. They also pay much better, and grant more reputation than does ferrying the peasantry.
Edit: I’d also put a regular 4A shield gen on rather than bi-weave. You’re not going to be fighting, you’ve got no weapons. You should be running away if attacked, and if so, you want your shields to stay up, and if they go down, you won’t be waiting around for them to come back up again.
