No, it doesn't fit. It's already a copy with a modified model – only the properties of the dolmen remain. I searched for it on RPGstats, but I don't think it's there (or something like that).

You didn't understand me. I'm not talking about copying the dolmen (i.e., it won't have the properties of the dolmen) and changing the copy's appearance to look like a dolmen.
For example, the Crystal of Knowledge. We copy it, change its appearance. (as a side effect, it gives +1 to knowledge) and so on. Moreover, we can take away this knowledge from heroes, and this procedure is painless for the hero, unlike the procedure of taking away experience.
Or, we can find another object that is more suitable.
