I am working on this exact issue. I want to plug the cooler ports and use an adapter of some kind to send oil forward to a remote filter and cooler arrangement. I don't like the sideways filter adapter that spills oil all over the dshaft, and I don't like the leaky stock cooler lines. The redesign on the cooler and filter ports started with Gen 5 in 1990ish. It's a pretty good design, but the drawback is the internal passages require the goofy plastic 'cage' diverter on the cooler-out line to separate the hot and cool oil passages. I tried to mod the stock filter adapter, but that wouldn't lay out the lines as cleanly as I wanted. I bought a Canton adapter which is a great part, but again it doesn't send the oil lines forward along the pan as cleanly as I wanted. So... I just happen to be a Solidworks engineer, so I drew one up that does exactly what I want. I'm having 5 made out of aluminum right now, and the extras will be for sale at my cost, around $100 each. It has two 1/2 inch pipe thread ports, just far enough apart to easily get 1/2 to -8 or -10 AN male fittings on, or you could use hose barbs for rubber hose. I don't have an image here on my home computer, but I can post one on monday.
