On this website at Cycling News they list the cassettes for several
bikes used in the Giro. A couple of them have Campagnolo 11-25
clusters. This is not a standard cassette offered to the masses. An
11-27 is listed for Shimano, also non standard. So it appears the
pros can and do mix and match cassettes to come up with whatever
combination they want. I suspect with enough money and cassettes you
can mix them any way you want. After all, all of the cogs have the
same spline configuration. Except maybe the 11 tooth is a bit
different. For your combination you would just start with the
11-12-13 from the 11-23 cassette you have and then add in cogs or
clumps of cogs after that.
In the past I have mixed a 13-23 and 13-26 together. The 13-23 had
some titanium cogs in it. I wanted to use these light weight cogs in
the 13-26 cassette. I really needed the 26 cog. They fit on the hub
just fine. But I could tell where the cogs changed from one cassette
to the other. Shifting was not as good on that spot. All of the
ramps and such do not line up well after mixing cogs between
cassettes.
