Unless your museum leadership came out and said it wasn't going to treat flying airplanes well, my interpretation is that you and they are saying the same things, just a different choice of words.
Example 1: If a B-17 needs new brakes, then they will likely be changed (by a maintenance team) using "specific operational and technical requirements of that object" - ie., the B-17 maintenance T.O.'s. That's not preservation, that's maintenance - but no matter how you slice it, the airplane remains historically accurate and safe.
Example 2: If a P-51 needs brakes and the staff decides to modify the airplane to use P-63 brakes, then the arument can be made that the airplane is no longer historically accurate, but that it is safer - and done so in a manner consistent with other P-51s. That's maintenance in lieu of preservation.
Example 3: If a Corsair needs to attend airshows and, in doing so, fly IFR, the museum may elect to re-do the panel with a Garmin G1000 electronic display. In this case, the plan for the aircraft totally diverges from artifact status, ie. a mod is added that is out of step with operational warbirds. This could be seen as a operational plus but a 100% historic bust.
Let's hope your musuem follows Example 1 when possible, Example 2 when necessary, and avoids Example 3 unless absolutely necessary.
That's my opinion.

Ken in general we agree, but as our policy is being presented for approval...
Using your examples
Example 1...We agree and the policy should reflect the regular maintenance facts
But as written the maintainer could change the brakes and the colour of the aircraft with no accountabilty to the curator or board.
Example 2...This one is a great examle of what I mean, with the policy as presented it would just happen, which I feel is wrong. A change of this level should have to be justified to the curator and board prior to any work being done and if operations require the upgrade happen approved by the board, documented as to the whats and hows and whys it was done.
Example 3...Is what I want to see the policy avoid, not the flying aircraft, but wholesale change without justification, approval and historic documentation.
Being a museum is different that a private owner...a private owner can do as they wish it is their aircraft.
Being a museum we have a mandate to present as much as possible a piece of history and be sure it represents that history properly.
As a pilot I will never oppose proper, safe and by the book service and operations...but a policy needs to insure the historic integrity and operational safety with accoutability.
My 2 bits...appreciate hearing other opinions and thoughts though.
