Hmm, I think コメントすることはありません is far more natural in this context.
もの in コメントするものはありません sounds to suggest concrete things, so it would have the nuance epigene-san wrote.
I haven't gone through all the other replies yet, but before I forget, I think the way you want to use もの is in the form of -teki na mono -的なもの. As to whether you can place mono right after a noun or not I can't answer that.
For example
科学的なもの would mean scientific stuff (science -> science-tifical -> science-ti-fical stuff)
女性てきなもの would mean feminine stuff (girl -> girl-ly -> gir-ly stuff)
"noun + もの" means "thing/work regarding~", or "thing corresponding to~".
e.g.
学園もの: campus-life story
ノーベル賞ものの発見: a discovery worthy of a Nobel Prize サービス終了のお知らせ
And following "no" as a possessive "mono" in the sense of "owning or being owned by", I like the translation "To such-and-such belongs the XYZ." A bit grandiose but as a set phrase or setting somehow fits the occasion. We see it in religious quotations for example:
Instead of boring old "The battle belongs to Jehovah" flip the subject and object to get "To Jehovah belongs the battle" : "Tatakai ha Yehoba no mono." Nice.
