That's an interesting list, and I'm honestly curious about the questions I've edited into it in bold print.
Going by the full list as written, Talislanta seems to be your dream game, unless maybe you count the kajillion species/profession classes as subclasses, which they sort of are and sort of aren't - more like BECMI's Elf "racial" class to me.
1. Sure, cards etc. would work just fine. I've also used dice pools, rock-paper-scissors, and Jenga towers. It's all good. Dice are just easier and more ubiquitous.
2a. XP and Level are tied together, except when they aren't--some people use levels without XP ("milestone leveling," "benchmark," and so forth). I prefer to have both though, because it avoids a common "DM May I?" complaint that some of my players have. "DM, may I gain a level now?"
2b. When we aren't playing D&D, we're playing Call of Cthulhu...so yeah, we love us some incremental skill improvement too. We've tinkered with other types of character advancement as well, like the old E6 house rule, where you no longer gain hit points and spell slots past a certain point and gain feats instead.
3. Oh when I say "stats," I meant way more than just ability scores. I mean any one of a number of numbers that change over time, and affect each other. Hit points, luck rolls/save throws, wand uses, stuff to track. I need at least
some resource management to avoid handwaving everything, and to avoid that "DM May I?" situation I mentioned earlier. ("DM, may I use my wand again?")
4. Honestly, BECM D&D is my "dream game." I still play it on the side, and still with my old high school gaming group, over Roll20. We're keeping it Old School over here, no Renaissance needed.
