Rookie mistake. Latex over Oil

I recently painted latex paint over what I now know is oil based paint on trim in two small rooms. Sanding it down will be too time consuming. I had a guy come by that said he could paint over it with a Kilz paint/primer product and it would be fine. I'm having carpet laid in those rooms soon and I don't want to deal with paint peeling in the future. I was thinking about replacing the baseboards for piece of mind. Is that overkill? Will the Kilz work? Thanks.

I know of no coating that will magically soak thru latex paint to make a good bond with the underlying oil base enamel. I'd aggressively sand with 80 grit. That will remove most of the latex that doesn't have a good bond, then dress it up sanding with 120 or 150 grit, oil prime and then apply the latex enamel.
