Since no one else seems to have an opinion, I'll take a stab at this.

You probably can, but I would stick with fiber.  The fiber ones take less
force to crush and seal, so switching to copper increases the chances of a
leak (or of breaking the fitting from overtightening).

Same comment as above.

> Are these standard sizes?

I believe you should be able to find ones that work without too much
trouble.  Might not look exactly as original, though.  According to Peter's
web site, the fuel pump washers are 5/8 by 7/8, which would be P/N 95601A375
at MMC (though you might consider just buying them from LDPart, since MMC
will only sell a box of 100).

I couldn't find a listing of the size for the BW35 filler, but it shouldn't
be too hard to measure your banjo and find a washer that will fit.  If
necessary, you can open up the center hole with a round file.  Or again,
just buy the washers from a Triumph specialist : Paddocks has them listed
(P/N 158337
