Oooh, this has some awesome potential, REALLY cool stuff could come out of your comic -- your pacing is really nice even while remaining in the classic bordered format! I'm very much a huge fan of page layout and composition. It's something I get so excited about organising when I sit down to start a page - THAT SAID, I'm really a novice and sheerly enjoy the experience of setting up panels and experimenting with filled gutters. Here are a couple borderless/semi-borderless pages from my comic that could be a start to expand on what you have in mind.

This page is a full bleed from the bottom to balance and weight the intense rift of the timeframe cutting the characters' realities at the top. I used the zig-zag panel to direct eyeflow along the speech bubbles as well as from one figure to the other until its reconnected with the present.

This page bleeds in at the top and focuses on a sort of fluid, cursor-automation progression kinda feel. I broke up the panels at the top of the programme "playing" to infer its start-up. The pinkish glare-stars overlap the borders, including the one cupping from the bottom.

And this page spreads out into the gutters from middle panel. I use the antennae jutting from the character's head to link to and pace through the top panels while setting it behind the arcing bottom panels (to present action in sequence against dimension shift).
I haven't done many borderless pages but I can recommend Seeing Starsigns, Anarchy Dreamers and #Wafflefry for more interesting and dynamic full-page spreads that are border-free. Really excited to see what you do with Spire in its psychedelic scene!!
