That is not part of a solution, I’m afraid, but rather increasing the risk even further by blinging. The high grade Rapture set is currenlty selling for just over 4.1 B, which would effectively quadruple the value of the current ship+clone 
Moreover, it’s the cap capacity that is the main issue. The ship on TQ performs well enough with its existing cap (mine has 14257 GJ with 480 sec recharge currently), but not on Sisi (11406 GJ, same recharge). For prolonged lvl 4 missions the cap hovers close to 30% on Sisi in Bastion mode (worse when not in Bastion mode), meaning it is then ripe for the taking by neuters, something that gankers won’t miss.
If you watch the video from OP in Buffed Marauders in Action (Paladin L4 mission) closely for the entire duration, he is not rich on cap either and at some point drops below 50% armor, and that was even before the cap nerf was put on Sisi… Sure, it will still run lvl4s, faster even, but bob forbid you get a visit … And wasn’t this the whole point of this Bastion of War thing, to make them more sustainable ?
A carrot ? In the case of the Paladin it’s a rotten stick.
