I'm not sure if i understand your issue.
traditional ligaturing and kerning is applied when a node list has fonts
using basemode
\starttext
\startluacode
local hbox = nodes.typesetters.hpack("Hello World!")
context("%p",hbox.width)
nodes.flush_list(hbox)
\stopluacode
\stoptext

you can assemble a list of characters and then do an hpack on them
