I am building up a bike for hilly light touring, and I'd like to use a
mix of parts already on the bike and on the basement shelf. For my
drivetrain I'd like to start with a Centaur Triple crankset (50-40-30)
and swap the granny for a Shimano LX 26. Front deraileur is Centaur
Triple. Rear deraileur will be Shimano XT with a 12-34 cassette.
Controls would be Shimano D/A bar-ends, set for friction front and
indexing rear.

This will all work dandy.

Since this will be a travel bike I'd like to use an
SRAM chain with removable link. Does anybody know whether I should use
a Campag or Shimano style chain,

You're imagining a distinction that does not actually exist. Go with the
SRAM PC59.

and whether or nor this kludge will
shift smoothly and reliably?

Yes.

Any "gotchas" that I haven't thought of?

Not really, though I'd prefer a Sugino XD crankset for such an
application, due to the better selection of chainwheel sizes available.
