Nope. Their threats tend to scale with them, or are just played differently. One of the key things to remember about high karma PCs in SR1-3 is that in addition to having high stats they had Karma Pools in the high double or even triple digits (even after permanently burning dice), and could re-roll their way to success on nearly every test because the statistical effect of aggregate karma re-rolls is like reducing the Target Number of huge TNs to something achievable. That's why GMing them requires you not to target their stats, but their Karma Pool.
Anyway, Lofwyr would just be
a lot more powerful than he is in
Street Legends. As far as I'm concerned, the stats for Lofwyr, Hestaby, and Lugh Surehand are
nice starts, especially when you look at the stats for experienced operatives like Thorn or Samantha Roth who only have decades on the immortals'
millennia and yet aren't that far behind an immortal like Surehand who was already a stupendous badass immortal in Earthdawn. Though that may be why Surehand was interested in Roth.
Everyone I gamed with whose PC was over 1,000 karma, and some who were at even half that, didn't bother converting them to SR4.
SR4 is not designed for them.
I especially liked the one who could fly at Mach 5 and had a custom close-combat spell that was Touch Only, but with a base damage code of Light NAVAL and a Drain Code that would instantly kill most characters.
