Can Harden play SF and can Parsons play PF?

I'm surprised that McHale hasn't run with a starting lineup of:

PG- Bev
SG- Linsanity
SF- Harden
PF- Parsons
C- Dwight

Is this a plausible lineup that we can start games with? I'm very concerned that we spend the entire game digging ourselves out of a ditch we created in the 1Q because we only have one legit offensive threat (Harden) in our current lineup (since Parsons has been slumping a little bit). The only real solution I can find for this is to get Lin back into the lineup so Harden doesn't have to do all the work, bring Asik off the bench so we're not clogging the lanes.

But can Parsons really play PF against the rest of the NBA and can Harden or Lin really play SF? Even if they are mismatched, do you all feel comfortable rolling out this lineup for the sake of adding offensive spark to the team in 1Q?
