I was wondering if this will give reasonable results as I am only working with those metagenome reads that map to the reference. What do you think?

To get a proper answer you will need to provide a lot more information about how deep the sequences was, if this is an environmental sample or sterilized a with reference bacteria added, and how many biological replicates do you have?
Let's assume these are environmental samples, then I would recommend doing de novo assembly and mapping back to the assembly to get count data.
