And, a teenage version of myself in a PbP TORG campaign:

Actually have done this sort of self-statting multiple times before, in multiple campaigns. Always had different apporaches to it. For example, I've been statted up more as a warrior (barbarian or paladin) back in high school, while as I grew older, I tended to be statted up as a sort of wizard (or a warrior/wizard). An older, experienced version of myself crops up in old old friend's fantasy RPG (formerly D&D, now a thing of his creation)/fiction setting. Another old AD&D campaign had me & my friends as "false gods" (deified by a barbaric tribe due to our modern knowledge/tech/game knowledge) years after our initial appearance in the campaign (and some of my PCs were members of that tribe who worshipped these deities). I'm playing a teenage version of myself present during the start of the Possibility Wars in TORG. Another teenage version of myself was frozen & thawed out in the Cyberpunk reality. Superhuman versions of mylsef has cropped up in Marvel RPG games (both dice & SAGA versions), as well as in a Heroes Unlimited campaign (often as a Thor-like/themed hero). The only thing rather consistent with these versions is that I often wield a sword &/or warhammer, and use lightning/cold/weather-related magics/powers.
Sorta-recently, I've been trying to address this idea, esp. with the wildly different versions at different ages. For my homebrew D&D campaign, I intend to have some elements of past games crop up--how many RPG PC versions of my group & I showed up IMC. Because of this, we essentially become deified in the minds of the populace (who else but a deity could manifest in a variety of forms, displaying a variety of powers?), and various "relics" of the deities (e.g., lost/abandoned items used by the PCs) are scattered throughout the campaign world.
(As it is, our "deified" PCs don't grant divine power at all like an actual deity would; IMC, divine spellcasters draw power from certain Inner Planes due to their faith [so it's more in line with the non-deity worshipping philosophical clerics mentioned in the PHB, but it applies to all divine spellcasters, with a bit of Eberron-style pantheon worship]. Our "deified" selves just got added in to the existing pantheon).
I plan on running a Marvel SAGA campaign with this theme as well, though this time, the PCs will be amnesiac younger clones of the players (altered to possess powers), and the possibility exists for them to run into the "originals", as well as some dimension-traveling goodness where they can encounter the various other PC versions of ourselves. (then again, since Hasbro & Marvel have a sort of working relationship again, I may wait & see if there could be WotC/Hasbro Marvel RPG coming out down the line).
At first, we tried to keep the stats close to how we were (or saw ourselves with), but as time (& setting) allowed, we allowed for differences/changes when viable (e.g., the WLD characters were 25 point-buy, though we got a stat boost [up to 28 or 32 point-buy, I think] before we started; superhero games allowed for huge changes due to gaining powers; etc.).
