I will say that AD Malz bot is probably one of the most fun bot laners I've played.
Part of me thinks it's even more fun when you're dominating bot lane and the enemy sees your AD build.
Unfortunately, if you do poorly, it backfires and people assume you're trolling.
But yeah, AD Malz is a thing on Dom. Voidlings 1:1 AD Ratio OP.
That reminds me, whatever happened to Vesh? He loved AD Malz and Kat.
I also find Wukong fun. But I will admit that I have the most fun when I trick people with my Decoy.
Personally, I suggest playing your favorite champion (unless your favorite is Kass then pick your second favorite champion). Even if it is "unviable," play that champion whenever your team's composition allows. Yesterday's Trash Tier champion could very well be Tomorrow's Cheesecake Tier champion.
