Note the convenient SE facing alley and then playground directly
opposite, and the S facing road beyond it.

So, you're proposing street running? It's almost at street level there.

The key word is "almost". The tracks at City Thameslink are only HALF
a story below street level - that didn't mean they couldn't raise the
road and Ludgate Circus by half a floor to get round the problem.

Besides, it can be lowered. The tube has many many changes of height,
and the Waterloo and City certainly does - its not that far to the
river, but it lowers itself quickly enough to go under.

And with an extension, the depot itself can be moved - maybe to
somewhere more convenient like next to the actual mainline, with a
joining track, so that stock can be moved directly instead of by an
awkward arrangement of crane and truck. The former Necropolis station,
and the branch from the mainline to it, spring to mind as particularly
helpful, and fairly conveniently located.

Once the depot is moved, the track through its former location no
longer needs to be level - it can slope down, and there's enough space
through the location for the tracks to use get sufficiently below
street level before they reach a street.
