Go for it. I haven't seen Gairlochian's device. Might be interesting if someone could post a pic or email one to me.
The main problem, with scoping the 96, is that as well as d&t for the bases, you have to bend the bolt to clear the scope. That being said, there is a see through mount available for the 96 that will allow the bent bolt model to work, without alteration.
The Lee Enfield, is also a good hunting choice, much better than many would like to believe. My only concern was taking a $350, full dress milsurp and turning it into a $150 Bubba and on top of that, spending at least $100 to do it. In the case of the Lee Enfield, if it is full wood, put it on the EE and you might be able to trade it for a nice sporter, complete with scope. If it's already cut down, do your best to dress it up suitably for your purposes.
