In order to get true permanent perks you have to have the season pass and beat every single easter egg, well, atleast get every piece of every soul key, this then unlocks directors cut giving you permanent perks for every map
If you just want to get all the perks for spaceland, you still have to beat the alien boss fight, thats how youll get the 5th skull for the arcade machine, then to get the 6th and final skull in order to play the machine, you have to have a brute shoot his laser at the machine, thus powering it up so you can play it
Theres no achievement or trophy for doing it on space land so it to me seems pointless to even attempt, since you will still have to beat the main easter egg to even try to go for it
