Is a Research paper possible for proposing of a Methodology?
is a journal publication possible for...a methodology?


Yes, assuming the ability to add functionality to a tool - from data generated by the tool - is useful to others, and assuming outcomes can be (relatively easily) manually derived from the aforementioned data. Added functionality is presumably useful, so the former assumption can be dropped. (Some justification should be added to the paper.) As to whether outcomes can be relatively easily derived, that isn't obvious and requires justification. If you can justify, then the latter assumption can be dropped too, giving-way to my answer to the above question: Yes.
