I don't think it's worthwhile, since it doesn't hedge bets very well. An alternative sequence could easily turn out to be more than one

(I was thinking that thus far all the sequences seem to have been single-instruction; the options thus far seem to have been "rhdwr", "lw $x, 0x1000($0)", and some other reserved-instruction sequence.)

Anyhow, there goes my attempt at cutting through this particular Gordion knot. :-)
