If you want to influence OSPF directly, believe, you'll want an IOS version that supports PIRO.
A workaround might be using static routing. Years ago, I set up a pair of 3660 Internet edge routers, using 12.4 something and its OER (and OSPF on the interior side). I remember I used just a static route and OER dynamically injected to-Internet routes. Don't recall whether I was running BGP between the pair of 3660s. Do recall I no longer BGP peered with the ISP routers.
So what I'm thinking, if you can get the injected routes with a better AD then OSPF routes, it might work without PIRO. However, again, on the external side, I only relied on the static default, so it's not exactly the same situation.
