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
instruction, but still faster than a trap.
(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. :-)
