No it is not possible. I agree 100% with crobar. I love to use styro to insulate but I will not completly enclose the envelope in it. It does not breath and will sweat. I built my addition with styro everywhere except the roof where I used unfaced fiberglass. You have to allow it to breath somehow. I have two machines for blowing in cellulose and it is super what it does in the applications where you can use it. I also like to put it in attics on top of the fiberglass to bloke the air flow. We have many old homes like yours here and it is not an easy thing to get it right. They were not made to vent in the conventional way. It all went out through the doors, windows, and other misc. holes. I think you are doing it the best and most cost effective way by pulling down the drywall and using fiberglass.

A friend told me years ago that he made a rectangular sleeve from sheet metal, open at both ends. Working from the attic, he stuffed fiberglass into the sleeve, slid it down inside the roof cavities, then pulled out the sleeve leaving the fiberglass in place.

He must be a patient man! I think that would involve some measure of alcohol before resorting to explosives!

Do not think about insulating without venting.. you will rot the roof structure and have water damaged sheetrock or drywall. Drywall and plaster both allow a lot of moisture through. Even when painted with either enamel or several layers of Latex paint.. the barrier is NOT impermiable to moisture.. so you MUST vent..
I had to replace a whole roof on a house years back that had the eves packed with insulation.. all the vents were blocked, and the entire underside of the cool roof was covered with frost in the winter, and when it melted with warm weather,, the insulation got soaking wet, and the ensuing wet ceilings in the rooms... what a mess..
