Steve,
This idea sounds very interesting. If you went with a saddle tank or a side tank
loco, (say a Ruby!) then the connections could be solid, with no need to have flexible
connections, as you would need with a tendered Loco. Also the heat issue should be
lower, as the tank would be sitting right next to/on the boiler. If it were a saddle
tanker, then you could simply omit the insulation and lagging under the tank, the same
with the side tanks. The plumbing might be a bit tricky, but not too bad.
Just my two cents.

Steve:
Very interesting idea. In theory, with pressure equal in both tanks, the
water will flow to the boiler. The auxiliary tank would be a pressure
vessel, built to the same standards as a boiler. Shouldn't need it's own
safety. You'd probably have to throw more Btu's at the boiler due to
thermal "siphoning" through the vent line. Connections between the vessels
would be a challenge but could be overcome. They may have to be oversize as
well to overcome surface tension/line loss impeding the flow of replacement
water.
You will be denying yourself the opportunity to bond with your engine while
in operation:>).
