I would like to see someone manufacture an oil filter that looks like the original four-cylinder ones, but opens up to be able to use a screw on newer filter cartridge inside. I think there is a market for these type of filters.
As things are now, you have to buy a whole new replacement filter when yours needs changing.
I solved this problem with my trucks by using a 1950's style oil filter whose cartridges I can buy at the local car parts store. But, I'd prefer a filter that looks like the original (just not the price of a new one).
Here's a link to a discussion of my oil filter usage:
