I know what you are talking about. I just had my lower hose blow on me and was going to get an new one and would have to buy those connectors. The dealer calls them oil cooler repair kits. But for $30 CDN for the repair kit, that only comes with 1 connector. I opted for buying a $3 splice and to clamps, and repaired my old one.
As for what you want to do, I think there would be no problem with replacing the ends with just hose.
