There is some precedent for Lego bringing outside ideas in. Adam Reed Tucker started doing architectural models outside Lego before they brought him on to create the still-running Lego Architecture line. Earlier sets even had his name on them. Chris McVeigh (aka Powerpig) had a website selling custom sets he designed, including retro computer sets, and a line of “brick sketches”. He’s now a designer at Lego. His Brick Sketches are official sets, and he’s designed retro computing adjacent sets too (including the new Atari 2600 set). There’s also the very successful Lego Ideas program.
