A and C, Grob themselves evidently considered a Ballistic Recovery System (airframe parachute) as seen in this G115/120TP marketing presentation of theirs, on page 10:

Figures for the Cirrus and Cessna 182 BRS systems indicate a weight between 79 and 85lbs.
Looking at the cutaway of the Tutor
http://www.eaachapter837.org/pages/m...15-cutaway.jpg suggests that connecting a strop to each spar/main leg would be possible, with a third line going under a frangible fairing to the top of the firewall. Frangible fairings covering external strops would be the easiest way of achieving this without the trenches in the structure used by Cirrus.
If firing the parachute out the top is impractical for the reasons you describe, then firing it out one side or the other has to be the next best solution.
If there was a will to fit an airframe parachute to the Tutor it could be done.

The AEFs and others used Chipmunks for years, with standard parachutes for cadets. That was viewed as satisfactory, with adequate briefing. What has changed - the attitude to risk ?
Recollections from ex-cadets who flew their AEFs in Chipmunks, include sitting on piles of folded up RAF greatcoats between their bottom and the parachute, to take up the slack in the parachute straps and to get them high enough to see out. Successful egress in an emergency clearly wasn't a priority then!
