They all support large RSA keys.  gpg even has an option
--enable-large-ras which is used at key egeneration time:

  const unsigned maxsize = (opt.flags.large_rsa ? 8192 : 4096);

It is easy to increase to 16k - but pretty please don't do that: it will
make the WoT and general use of signatures very annoying due to the
slowness
