Could USS Seattle's receiving-ship crew get her underway?

Could USS Seattle's reserve receiving-ship crew raise steam and sail her on a drunken bet during the Second World War?

Probably, because her machinery was mechanically straightforward, but it would take time and depend heavily on how well the engines had been preserved.

USS Seattle retained vertical triple-expansion engines and Babcock & Wilcox boilers after becoming a receiving ship. That machinery was mechanically straightforward by later naval standards, but bringing a long-idle plant back to life would still require careful inspection and sustained labor. A reserve crew could probably restore steam if the boilers, condensers, feed systems, and engines had been maintained. The task becomes much more plausible if an engineering chief had deliberately kept the plant workable rather than allowing it to decay in place. Getting underway is therefore conceivable, but neither quick nor guaranteed merely because the machinery remained aboard.
