I have met quite a lot of Scorpio rising people of various Sun signs (most common being Gemini and Aqua) and
... and what?
You're a little off there, in whole signs my Sun is in 8th house
I understand why you say Leos wouldn't stimulate you much. I feel the same way about their Sun signs... just big egos. In fact I was going to say that Sagittarius seems like the "full package"... they are fun, funny, sporty, adventurous, AND good looking (for the most part). But again, we're not talking about qualities, we're talking about actual physical appearance; just picture each rising sign as mannequins.
I actually love Sag rising people... but they bug me in just two ways: They CAN'T SIT STILL! This is ironic since I am a Gemini and a social butterfly, but when I'm at a party or similar event, I find one corner of a room, and just stand or sit there for the entire evening (until I get up to dance, or say hello to someone, but mostly I just return to that spot, and people know to come find me there to chill because it has become 'my' spot). This also contributes to their spontaneity. I was out with a girl who is a Taurus with Sag rising once. Within a few minutes she wanted to suddenly get up and go on some "adventure", while I just wanted to sit, drink, have a riveting conversation, and listen to some music. Eventually, she asked me where is my spontaneity. I retorted that of course I am (thinking that I'm a Gemini, so I should), before I could finish she pulled me in for a kiss which jolted me lol. It kind of bothered me, but it was nice.
Oh and the other thing that bugs me is their sense of style... of which (unless something else in their chart helps them), they have none. A jeans or shorts, t-shirt, flip-flops or tennis shoes, is not style. This what I love about Leo rising, lol.
My MC is in Leo. If I'm not mistaken that would be reputation, public image, etc. For as long as I can remember, I have always held that honing a proper public image and reputation is extremely important, and for me, doing so would mean knowing how to "shine": dress, speak, carry one's self like royalty. "Life is a show and we are all participants and spectators" I either tweeted or facebooked some years ago.
Since I analyze charts in Placidus my sun in the 7th house ruled by the 10th means that I want to see this in others, and not just myself. I haven't gotten into whole signs, so I don't know how to analyze my Sun for the 8th house. I don't see Leos as "healthy" as you put it. Moon would be in my 6th house, in whole signs (5th for placidus). I do find Cancers rather comforting and having a holistic energy when I think about it. I will have to stop here before I confuse myself trying to interpret a different system lol.
