Honestly these would be pretty usable! I'm fairly art-capable so color shifting and matching won't be the biggest issue, as long as I have something to work with- and this would indeed work! Thank you for taking the time to do these!
( And no worries on unprofessionalism or anything like that- it's admittedly an odd request + most people don't keep their files for years at a time. I'm glad you could do what you could! )
