Thank you so much, relist and SIMPLIFY both work.

Yes, this works exactly as needed. I had tried this, but I failed to
notice that you could supply the skeleton argument separately. Thanks!
I had also tried
mapply( "[<-", l, "a", c(5,6), SIMPLIFY=FALSE)
but failed to put SIMPLIFY in all-caps, and got an error message that I
did not understand. It seems I was close on both methods, but not close
