Hey Evan,
Just to play devils advocate, maybe you shouldn’t even show these as full projects with process.
Based on your description/energy level around the projects it sounds like putting effort into backwards engineering some exciting process; and BS’ing someone else through it during an interview is probably going to do you more harm than good. People pick up on that quickly.
Your portfolio is a chance to show what you’re interested and passionate about, and a chance for employers to evaluate your potential for growth (especially for junior positions). If these project don’t reflect what you’re about or the type of work you aspire to do , I would put your effort into new work that does.
Keep it simple, use them as bonus work you can show during the in person as examples of your professional competency.
