I know that Seattle converted at least one tunnel, which was
originally to be for a light rail line, into a dedicated bus lane.

I've not seen, however, anything like this.

The problem with a Holborn-Aldwych cycle route is that unless the
Holborn end is for Piccadilly Line passengers, the round trip
surface-tube-surface will take longer than walking. And don't let us
forget one the main reasons Aldwych closed was it was too expensive
to repair the lifts. Finally, what about the tidal flow of
Boris-bikes - what tooth fairy is going to be shuttling them back to
the other end so that more than a couple of dozen people can use the
route each morning or evening?

It's obvious - you run a train on the other track to take the bikes
back!

Although built for two tracks, there's only one, and also massive
restoration work would be required to bring the second platform at
either end back into use.

Then that's the one the cyclists go in, silly! ;-)

That's the bore I was referring to when I said the others were in railway
use.

What I haven't been able to establish is whether the tunnel(s) between
the two stations [Holborn and Aldwych] are two bores, or a larger bore
with two tracks in. Traditionally it would be the former.

Perhaps boring experts could comment? (see: Yellow Pages).

Definitely two bores, like the rest of the Great Northern, Piccadilly &
Brompton Railway.

Having spent a bit longer looking at websites yesterday, it's single
tunnels but there's a step-plate junction with X-overs at Holborn.

It's not just the platform, it's the whole station tunnel. Add to that
the "closed" platform-tunnel at the Holborn end is significantly less
accessible than the other (which was used until closure in the 90's)

In terms of usual railway work it would IMU be more a case of
de-cluttering than major reconstruction although I'm not sure if the
Holborn end was ever actually "finished off" WRT connecting the twin
tunnels to the main line as the connection at Holborn only seems to
have led to the westbound line.

Is there any chance of reactivating Holborn-Aldwych for revenue service?
Or are the lifts the main factor, killing that prospect?

They could, for example, run a crewless train in there.
