Super Mario Bros. Wonder as we know was able to have introduced to Mario a power up that shoots bubbles, of which had previously been in ROM Hacks for Super Mario World along with existing ones from at a certain point: https://www.reddit.com/r/Mario/comments/166cy08/the_new_bubble_form_in_super_mario_bros_wonder_is/

Since the Bubble Flower was able to become a reality in official Mario stuff even as far as working the exact same way, something else from that ROM Hack should become a reality as well in whatever Mario's next 2D Adventure that's not a sequel to anything ends up being, of which is the Electric Flower, a power up that can enable to shoot balls of electricity which as well as defeating enemies could maybe also be used to power things.
