trying to diversify my pool

So this is actually two questions as I play two roles primarily, top and support.

The question is which champion for each role that would be something similar enough to the ones listed to make playing him enjoyable but still different enough that it diversifies the picks im comfortable with for different comps

For top lane i seem to do best with a heavy harass ranged champs that can out sustain in lane, I prefer ranged champs in general and am ok being a bit passive to scale into late game, currently my comfortable top picks are and

For support I seem to prefer decent damage ranged supports, i like to be able to engage heavily and really bully my lane, I tend to try and snowball lane and again, prefer ranged supports. I do dislike being so squishy but find that melee supports often lead to being pushed under tower in lane. Currently my supports are and the occasional off meta

So I will raise the question to smarter men than I, and as u can see I have a lot of AP champions overall and could use some AD in my life...who's next folks?
