Optimize & Translate Minecraft Pixelmon Generations 1.12 Mod to new Pixelmon Generations 1.20.1

I have worked with volunteers to make a custom adventure map of around around 11,000x6,500 blocks focusing on a Pixelmon Generations 1.12 mod. This mod has been retired and the new owners have changed Pixelmon Generation to a 1.20.1 mod as a sidemod as cobblemon. I would like to update the world save in an -as is- state. All of the blocks should have equivalents on both, including block states or orientations so I would expect this to be translated. As Generations is currently in Beta, this posting may require follow up should the developers further alter their source. However the current scope only exists for 3 goals: 1) Creation of a sidemod for the ~250 blocks removed by BiomeOPleanty mod 2) Creation of a string mapping between the existing world download blocks to all of the equivalent blocks including those in the sidemod and Pixelmon mod and translate the world file to a 1.20.1 world 3)Package all required mods to run, and the world file and return them in a reasonable timeframe Ideally I'd like to find someone able to take the world download provided and return a complete world download The current world download runs on: BiomesOPleanty 1.12.v2-7.0.1 Optifine 1.12.2 Pixelextras 3.2.4 Pixelmongenerations 1.12 v2.6.7 and the completed world should match all of these mods to a 1.20.1 equivalent (except Pixelmongenerations 1.12 v2.6.7 as there is no 1.20 version) and add the new Pixelmon Generations mod and its dependencies including: architectury 9.1.12 botarium forge 1.20 v2.3.1 cobblemon forge 1.20 v1.4.1 Generations-Core 2.1.1 Beta Kotlin 4.10.0 Returning a complete world download would mean one without missing blocks in a state to be played for the currently loaded chunks in the Overworld, Nether and end Dimensions. This will likely include development of an additional sidemod to bridge the blocks missing that were removed by BiomesOPleanty. This sidemod is free for you to keep and repackage in any capacity, but we do ask that the contents of the world download including builds and information be strictly confidential. In addition to financial compensation for the work, we will also be able to credit your work in the world if so desired upon distribution.
