I don’t slide, but have found slide gloves work better for me than wrist guards. On the luckily few occasions that i’ve went down skating, i pretty consistently first impact the heel of my palm and then roll. Wrist guards do the best job for me to absorb that impact, but they are a pain to wear - can’t wear a watch under them, and cover a lot of the forearm so are hot/sweaty. (getting to my point slowly - sorry). So gloves are more likely to be worn even if slightly less protection than the wrist guards.
I got a set of holesom cords gloves and am able to place the slide pucks a little low on the heel of my palm allowing me to grip my remote easily at the same time. I’m not sure if the placement would work for your use, actually sliding on them at the same time?
I might also look at @FLATLINEcustoms “mad munkey” GT2b enclosure - as it has a nice flat surface on the side of the Tx that could attach a slide puck to? Even drilling out some holes to access the controls i think would work.
