Who cares what it would encourage/discourage. If someone wants a Borg cube, they're going to build a Borg cube. Fact is, boarding is going to be a rare event in any case, unless you happen to have built a highly enviable ship that everyone wants. They might try to take it from you. So build some internal turrets to protect yourself. Come up with some interesting ways to defend your interior. Stick your ship on auto-pilot and go shoot the boarders with your laser. Maybe have some cameras set up inside your ship at the end of some corridors with a shotgun set up and manually mind them and remove them. There's a lot of creative solutions.
Also, I think it would be beneficial to have some Sticky blocks that would grab on to a surface loosely. It could be like magnetic landing gear that sticks to hulls and if it's bumped or shot at with a certain power weapon, it would be thrown off.
