Welcome to the Forum. That's great you're thinking about attending the Convention!
Before you go all crazy on dumping all sort of time and money into your conversion project, you may want to push the pause button and have a moment. Here's the way I see such endeavors. If you love tinkering and building things and have the technical and financial resources to take on such a project, then go for it. It will be a great learning experience.
If on the other hand, you're lacking any of those things, it may be wiser go another direction. Fluff up what you have, drive it a bit and flip it to buy a factory made SR car. It will be way less hassle in terms of labor and dollars. Using that strategy, may actually get you into an SR car sooner. I guess it really depends on how deep you want to get in the grease. What you're proposing is very ambitious, even for a seasoned wrench. 2cents from the old guy, for what it's worth.
