I'd prefer to make them liquids, and preferably reusable -- good solids
aren't as cheap as they look, and moderate-performance liquids don't have
to be expensive -- but yes, it's a defensible idea. Provided, that is,
that the strap-ons are *only* for unusual cases; otherwise you're really
building a TSTO, and you will get a better design if you're honest with
yourself about that.
