It's possible, and we did some experiments on this some years back, but
found that the gains weren't significant under that combination - but we
weren't about to figure out why.  I don't have the precise details to
hand of how to arrange this build, but it is not hard.

We'll need to work through the issues.  I think that this is a better
solution, as it helps everyone.

Don't forget to add Q2 to the autobuilder.
