not with a lot of effort on my end which i'm not willing to invest in 
something that is just a hack for bad input ... tex has no spaces so 
then we need other magic

anyway, i added a bogus lookup to the font handler that will remove 
characters so in a next beta you can do this (some upbeat music in the 
background so i could convince myself)

\startluacode
      fonts.handlers.otf.addfeature {
          name    = "crap",
          type    = "chainsubstitution",
          prepend = true,
          lookups = {
              {
                  type = "multiple",
                  data = {
                      ["v"] = { "V", "í", "a" },
                  },
              },
              {
                  type = "multiple",
                  data = {
                      ["c"] = { "c", "/" },
                  },
              },
              {
                  type = "substitution",
                  data = {
                      ["c"] = "C",
                  },
              },
          },
          data = {
              rules = {
                  {
                      comment = "'via' => 'Vía'",
                      current = { { "v" }, { "i" }, { "a" } },
                      after   = { { " " } },
                      lookups = { 1, 0, 0 },
                  },
                  {
                      comment = "'calle ' => 'c/ '",
                      current = { { "c" }, { "a" }, { "l" }, { "l" }, { 
"e" } },
                      after   = { { " " } },
                      lookups = { 2, 0, 0, 0, 0 },
                  },
                  {
                      comment = "' calle' => ' Calle'",
                      before  = { { " " } },
                      current = { { "c" } },
                      after   = { { "a" }, { "l" }, { "l" }, { "e" } },
                      lookups = { 3 },
                  },
              },
          },
      }
\stopluacode

\definefontfeature[default][default][crap=yes]

\starttext

\startTEXpage[offset=2em]
     \type{text:} \type{calle via del viaducto de la calle}

     \type{done:} calle via del viaducto via de la calle

     \type{okay:} c/ Vía del viaducto Vía de la Calle
\stopTEXpage

\stoptext

one could make a constructor for this but would hide the weirdness of it 
... yet another obscure feature
