How can I activate an area of redstone all at once?

The idea behind my contraption is to trap players in lava by deactivating an area of fence gates under some carpet. This pushes the players upwards into the lava and there items fall onto the carpet. (Basically killing a player with lava without burning their items.).
My problem is that I'm not sure how to toggle the full area of fence gates from the underneath.
(Where the grass is below the fence gates.).
The solutions I thought of are:.
I can try and toggle a bunch of redstone torches underneath (due to them activating upwards), but then how do I activate the torches?
Observers also activate upwards, but for only a tick, how can I make it on/off like the torches?
If you have any ideas on how to fix my issue, please share them here. If you have any redesigns for a more improvised trap, please put them here as well. (No commands/No mods) Thank you!.

Answer:
While I wrote my last comment, I had an idea that's at least not overly terrible. It works with arbitrarily large planes, is "just" 6 blocks tall and at most 3 blocks longer in one direction and 1 in another than the area you want to toggle. That's already way better than another else I could think of.
The idea was to use slime/honey blocks to increase the amount of redstone blocks you can move towards the fence gates at once, basically shrinking the problem of how many blocks need to be powered at once. Theoretically you could use 6 slime/honey blocks and 6 redstone blocks each, but due to the eternally annoying bug MC-108, this doesn't work. The redstone blocks need to be even further away from the pistons, so you can only use 5 redstone blocks per piston.
You could use a similar method to power up to 11 pistons at a time with redstone blocks, but then the circuit would grow even further downwards.
You can make the rows of redstone and repeaters longer between the parts where the signal snakes around, to use the full power level 15, and you can infinitely tile this pattern, alternating between slime and honey blocks wherever they touch.
There's probably a way to make the redstone/repeater part a bit more compact, but it's probably usually not worth it.
This all looks really messy, but it might be the easiest way. A similar problem are 1×1 lamp screens where every pixel can be controlled individually, which experts have worked on for years. Those contraptions can get extremely complicated.
In general, whenever you can avoid this problem, do that instead.
