If credits were scarce and fuel and repairs properly scaled:Perhaps it would be prudent to test new system, but at start do it with attacker. So for party making interdiction: No logging out, and no waking out as long as there is other ship in instance, be it cmdr or NPC police. Lets see how fun that would be. Better be fast swatting out those cops to make escape.
Traders would make the money, and be able to buy bigger and more powerful ships
Mercs would then be a natural hire for protection, and be able to afford decent ships
Pirates would scratch a living, the best being those who keep targets alive
Gankers would slowly lose out, having less money to spend, increasing bounties, and smaller ships that are always in disrepair.
Since gankers have no income stream (bar Powerplay orother niches) having small ships makes them much more vulnerable to C+P, BH, security and ATR, but especially against players with better ships.
Couple that with self awareness and skills, it would go a long way to do things subtly.
