Why not just do e1$e2$a <- 3 ? If you are trying to do something more complicated, it may help to understand that e1 %:% e2 %:% a <- 3 is effectively the same as tmp1 <- e1 %:% e2 tmp1 %:% a <- 3 tmp2 <- e1 tmp2 %:% e2 <- tmp1 e1 <- tmp2 so your %:%<- function is going to get called multiple times.
