My friend is really interested in this concept and I think it has some real merit to it. The main thing is that Garands are plagued (in the department of telescopic sights) by their top loading. The scout scope would solve this issue and bring all the benefits of a scout scope to the Garand platform.
Because light weight is typically a scout trait, he was thinking he would get a synthetic stock and a .308 barrel. He wondered about scope mounting and I told him that I think you'd have enough material to set up a two piece scope mount on the thick part of the barrel. The problem with this is you have to remove that top handguard, but I thought about it and I think you'd be fine if you just cut away enough of the material to expose the base.
One question I had though, would he be ok with just getting a barreled action? This is what I initially suggested to him, but then I realized that I don't know if they come with trigger groups or not. Do they?
Oh and one more noob question - in .308, do you use the same en bloc clips?
