I know how original routing credit works in general, but if I am re-accommodated (due to bump, mechanical, whatever) from my original airline to one of their partner airlines, can I obtain original routing credit AND credit from the flights taken and have both posted to the same FF program?

Specific example: I'm a DL GM. This weekend I'm flying ATL-MSP-SFO on NW and crediting to DL. If I were to take a bump and be accommodated on the DL non-stop, I'd definitely want to credit to DL and try for the upgrade on ATL-SFO, but that'd be less EQMs than the ATL-MSP-SFO routing which I'd also want credit for. How to handle? Can I get both?

(Of course I'd be hoping NW books me in the Y bucket on DL, at which time talking just the DL flight credit would exceed the original routing - but I'd still be happy to take the original routing too!)
