Is there a place for publishing ideas (no tangible results)?
While you might struggle to publish something like this in a journal, in Computer Science there are other venues to look out for, such as conferences and workshops. These are smaller (and sometimes less prestigious) than journals, but usually with a tighter focus: you can often publish work-in-progress or position papers. 

Edit: Some conferences are large, prestigious events, and will expect a substantial contribution to the field, so before you decide where to submit, take a look at past papers, and the sort of thing they tend to publish.
