I don't have a lot of familiarity with the Gen1's, but my understanding is that it's a larger and higher-voltage pack, because it doesn't have the SEPIC converter.
I reverse-engineered the Gen2 Battery control module with only a week's worth of work and was able to completely replace it in my Gen2's PHEV upgrade with an LFP pack. I'd guess it should be similarly easy on the Gen1, but it's a lot of work to put into such an old car at this point. I don't know what the Gen1's powertrain limits are. I've heard that insulation breakdown on the windings have killed a lot of them though.
