It will never work, never!!!!!!
Hang on, no..... that would be bad for me....
Just kidding. I think it sounds like a good idea actually.
The turbo does use up some power so some extra fuel might be needed in the end to realize all of the gains. I'd try it as is, but you might need to use the TD pump in the end to get some extra fuel on boost without making it smoke off boost. Then just keep the wastegate backed off so that the boost is low. We are at around 2 psi below see level pressure here and at 7000 ft is would be 3 psi. So maybe 3 psi boost would be a good choice to start with.
