Mods + suggestions for puzzles

Anyone have interest in Mods?

I'm currently working on a Portal 1 mod called Delta Final and wondered if you'd have any suggestions for puzzles.

Here's a few caveats and stuff.

You have access to all Portal 1 mechanics, the custom lifeform sensor, and a janky Excursion Funnel.

Note this excursion funnel can't go through portals and will push you out of it if you reach the end. (Have you played Portal Unity? it's the MID funnel from Portal Unity basically)

I'd appreciate it if one of these chambers did not use the lifeform sensor, so if you have multiple ideas keep that in mind.
