My understanding of the time line. The p500 project was another in a long line of colour pet project to satisfy Jacks desire to have an apple 2 killer. The chips were started in January 1981 Yashi Terakura became aware of the chips at the same time as engineers in the US were arguing that what people wanted was a VIC20 sequel and not an apple 2 killer. The Max and the C64 were started at roughly the same time, but there was more work necessary for the C64. The chips were finished in November 1981 The C64 and P500 being shown at January 1982 CES. Although the C64 was called the VIC-40 and the p500 was called the commodore 64. The Max was then launched along with some software. The C64 was launched in August 1982. I have no idea when the C64 gained ultimax mode and the memory map & cia hookups became compatible. It certainly wasn't the case that there was a finished max machine design that they started with to create the c64.
