Indeed he would.
Which wouldn't help him much in the comic, because Iron Fist is written as a top tier martial artist who happens to have a super charged fist. Danny wouldn't go swinging wildly in comic as he did against Elektra, he'd light that sucker up and let Cap try and come to him.. (And it isn't supposed to be a big swing haymaker anyways. Chi amp should let a little quick jab turn Cage airborn, as the chi's doing all the work and not the momentum of the fist..)
TV Danny is written more like an upper mid range martial artist who relies on the fist to bail him out. I guess the TV people, whether it was script writers, producers, or whoever, figured Matt would be irrelevent if Danny was at his level, plus had the chi smash, hence the brief scuffle with Matt having a clear advantage.
