My approach:

The advantage of using an aluminum backing plate with nutplates is that you can snug the bolts anytime you feel the need. Torquing bolts, even with washers, into lead is potentially problematic as the lead is soft and easily deformed - if it gives way a bit more over time, bolts can work loose even if the nut hasn't turned. Bridging the two holes with harder material and using nutplates addresses these issues.
