The only two things I can think of are a possible spoiler on the trunk, if it was the right shape, to help with aerodynamics. Or, I've seen spoiler-like things go on the back of a lot of newer cars right above the rear window. That would be similar to a mini-camback? Right? Would something that small even make a noticable difference?

If I had an SL1, I would either be :
1 - Studying the "Evo Vortex Generator" solution (what you are talking about). The idea would be to have vortex generators that help "bridge" the gap to a spoiler that helps your aerodynamics. Here's the Evo paper :

But, the likelihood of MPG payoff would be much less because the Evo solution was designed for downforce (I think), and was heavily engineered.
2 - Trying to fab a removeable Kamm-Back, probably using lots of magnets. The roof and trunk lid on the SL1 is metal, so you could work with that. The key would be a design that gives you a correct shape *and* ( relatively
) easy access to the trunk.
If I can find a good side view picture of an SL1, I'll do a mockup.
