Editor's comments differ from those of reviewers
It's the editor's call, and since you have no right to get your manuscript published, you don't really have a basis to ignore the editor's request -- if that's what the editor wants, then that's what you likely have to give him/her.

That said, while the manuscript management systems most journals use typically give you a deadline by which you have to turn around revisions, these are not actually enforced. That's because if you need to, you can always let the deadline pass and submit your revision as a new paper -- if you mention in your cover letter that it is a resubmission of a prior manuscript, then it will go to the same editor and from that person likely to the same reviewers.

The better approach is to discuss the timeline issue with the editor. Email the editor back and state that you're looking forward to making the requested changes, but that you can't do it in the requested time. Ask whether you can get an extension, stating how much time you need. As an editor, I can't see a reason why that should not be granted.
