There isn't really anything we can do here.
Modifying EDIDs would be something that needs to be done deep down in the linux kernel and that has a high risk of breaking things - just look at the cheap chinese HDMI audio splitters which modify EDID on the fly and break stuff because they didn't get it 100% right.
Also adding modes that are not supported by a monitor may at best confuse users (I did a test with your EDID and my monitor didn't like 1440 × 1080 and 640 × 480 96Hz modes - signal out of range) or even worse interfere with kodi's whitelist because it may pick one of the additional modes instead of the actually supported modes reported by the display.
The way forward is that you create a curated, known working set of EDIDs that pepole can choose from - similar to what HDFury is doing, see eg https://hdfury.com/tools/HDfury_EDID_collection.zip
People can then pick one of those EDIDs that match their setup (eg either 1440x1080 or 640 × 480 96Hz), verify on their own that it really works with their display device and use one of the standard methods to inject it - either the edid override you get "for free" with linux, with an external "EDID fixer" device like the HDFury Dr.HDMI, VRROOM or similar ones, or by patching/reprogramming the HDMI sink (the latter would risky and often might not be possible to do though).
so long,
