I’ve closed the poll because (a) there have been reports of alt accounts skewing the result and (b) the discussion below has produced more interesting/viable alternatives , making the current selections outdated.
There will most likely be a second poll with updated options in the future (which will also be stricter in who is allowed to vote).
I will also look into if/how any of these suggestions could be retrofitted in one of the three existing families (in conjunction with About the current state of spacecraft in the game , which sadly I haven’t had a chance to fully look into yet)
