Smurf - I'd be team leader of course. I wouldn't be the team powerhouse, or the bookworm, but have that "Captain America" quality. A decent strength level, mixed with agility, MA, and maybe an extra or two. Like Spiderman meets Ironfist. Power wise? I'd imagine myself as Spiderman-level. Above a street-leveler, below your Ironmans and Thors.
Digi- Digi would be my co-captain. The Ironman to my Captain America. Also, like Ironman, he would be a fairly heavy hitter. Definitely a flier and a class 70-100. But I think he would have more hereditary powers than Ironman. Like a watered down Thor.
King Mungi- The brains behind the group. Mungi would be the analytical, COMM link updater, Mr. Fantastic-esque. But, he'd be less of a dork then Reed. And with a decent power level- probably a mutant, actually. Also a flier. Energy manipulator. Like a good-willed Magneto.
Soljer- My tactical coordinator. He wouldn't have memorized the first 100 digits of Pi, but he would give the orders for the dirty, life-on-the-line situations. Probably have a history of Black Ops training, and would shoot to kill. Also with physical enhancements, and cool gear. Like an American Black Panther.
Capt it Up- Capt would be the team loner. He'd have the dark side of the group, with the shady background, but still respected. Probably some sort of ninja/chi training, mixed with a couple meta/mutant powers. Something of a male Elektra, or a more powerful Daredevil.
Bigbran- The true team powerhouse. He'd be smart, but not the absolute brightest, and have a sense of dark humor. Class 100+. Like a smart Hulk. Maybe with a bit of flexibility and variation power wise.
Xmarks- The team telepath, and only girl. Probably a feminist, with high level mind-f*cking capabilities, probably from mutant genes of some sort. Fills the "we know we need 'em, but the piss us off" role. Also the team hottie. I envision tight leather.. droolio
*note: see Emma Frost
Martian Mind- The untapped potential role. Probably the "just a kid" role too. He'd have the required naivety and innocent youth qualities that are a must for any successful group. Probably an Omega Mutant, with either energy-based powers or 'other' powers ala Darwin.
