What you can do is something like

bmajoraccidentals = { c cis d dis f fis g gis a ais }
\modalTranspose c cis \bmajoraccidentals \relative {
    \key b \major
    b c d e f g a b
}

So you don’t even need a new function. But that’s very unflexible as it
doesn’t allow you to enter pitches other than b cis dis e fis gis ais,
bis, eis, and all the flats. But you won’t get it much more flexible
even with a new function.

A even simpler way to do this (however with different midi output):

\relative {
    \omit Accidental
    \key b \major
    b c d e f g a b
}
