You will still have the original hotlink file (building.pln) so you can still use that if ever you need it again.
But breaking the hotlink in the site plan will mean you now have editable elements in the site plan with no link back to the original file.
So the original file is now really obsolete.
Personally I would try to keep the hotlink seeing as you already have it there.
As you mentioned you can turn layers on and off (create layer combinations) so you can get the views you want and you can also set up your sections and elevations in the site plan file as well - but there is no need if you already have them in the original building file.
You just can't turn off the master layer that the hotlink is in because it will hide the entire hotlink regardless of what other layers you have on.
If you need to edit the building just do that in the original file, save and then update the hotlink in the site plan file.
Keeping the original building file as a hotlink means if you have sections and elevations set up there already you do not have to do them again in the site plan - sections and elevations do not come across with a hotlink.
You can even have the two separate files but only one layout book (in either file) as you can link a drawing on a layout to an external source.
i.e. you can link the site plan layouts into the building file.
In fact you can open the Organiser, in the building file, open the site plan in the left side and view the layouts and drag the site layouts to the building layout book on the right side and all the external links will be done for you.
Saves you linking manually.
