The idea isn't to raise more because you have a big hand. You raise more because there are limpers (so the pot is bigger) and - most importantly - you are OOP. I would raise the same amount with any hand that I chose to raise in that spot, be it AA or 23o.

You need to raise occasionally with other hands besides your big pairs to balance your strategy and protect your big pairs from guys taking shots at you because they know what you hold. IMO, you do that most effectively by raising a wider range, not by raising less to disguise the strength of your hand.
