There are two ports there already. There's physically not enough space to make ports for doing a proper oil cooler setup.

You'll have to design and supply the two gaskets, of course, but this would at least eliminate one of the many headaches and sources of potential RTV clogging while making it user serviceable for the future.

Been there, done that. They don't work for a number of reasons. The pans aren't that flat and too flimsy, the FA sealing surface is too small, the bolts are too far apart, etc., etc... We've done o-rings, rubber, and cork. I would recommend none, unless you are removing the pan a LOT. When I say a lot I mean after six rally stages, or after a few drag passes... stuff like that. We do use them, but ONLY for short term stuff, like oil product testing where the pan comes off every 6 dyno pulls and that would happen a dozen times over a week. We use them then as a time saver, but they do not hold up much beyond that.
Another benefit I didn't state in my OP, is that this spacer is very thick and is going to have machined surfaces. You can use FAR less sealant when installing the spacer, and also inspect to see how much has oozed into the inside. Additionally, you could use your finger and remove and excess that oozed inward if you wanted to. The spacer also has a wider sealing surface than the block, which should mean a better seal with potentially less sealant.
