Renovating dull stairs

[Chellios]

Hi housemates!
I'm considering freshening up our stairs down to the basement. We have a finished basement with a laundry room and a rec room, so it's used a lot.
It would be fun to freshen up the stairs down to the basement to get rid of the basement feeling.
My question is if and how you can remove the risers in the staircase. Does it look better? Does it feel more airy?

We're fixing a water damage if you're wondering about the pictures.

Nah...
What do you have behind the stairs?
Are you down there often?

No...
What do you have behind the stairs?
Do you go down often?

Behind it is just a small hallway, the basement room is mostly used as a living room daily.

I wonder if it's not mostly work for essentially nothing to remove the rise steps...
It could be that they are part of the staircase's structure, so it would be weird to remove them.

Looks like a well-made staircase. Risers may be needed to prevent the treads from flexing and starting to creak. The inner curve's attachment is far too narrow to manage without a riser.

Replace/renovate the stair nose with something wood-colored and replace the synthetic carpet with natural-colored sisal. It matches the well-made handrail and brick wall. Some warmth in the colors is needed.
