You can create architectural defaults for your own use:

I'd have to scope things out more carefully than I have time for right now
before I'd add them to the main package, unfortunately . . .

Well, you are losing the benefit of 8 of the hours of tuning you just went
through :)  

If you use stock LAPACK rather than an ATLAS-tuned one, your factorization
performance will be reduced enormously on most platforms.
