I'm afraid, not really.

stem directly produces output, instead of creating an object. So that's the 
main problem. Also, rk.results() isn't designed to handle this sort of 
pre-formatted output.

HTMLstem solves the issue by first capturing the output of stem using 
capture.output(), and then printing it inside <pre></pre>.

I think, there's no way around using capture.output() to get the result of 
stem in a usable form. For printing, I've added the simple function
rk.print.literal(x)
which directs to the output inside of <pre></pre> (but will be extensible to 
support other output formats). So the call would be e.g.
rk.print.literal(capture.output(stem(islands)))
