Those blazers were very good guitars. I've seen quite a few and most of them are still in service.
Screening cavities with copper isn't a problem - the foil is so far away from the pickups and wiring that the capacitance is too high to affect the audible ranges. I've screened pickups directly and it has a small effect, but not so's most folk would notice. Aluminium foil can affect the inductance of the pickups though.
