I like your thinking.
I'm not a racer so can't offer a solution.
But it seems to me there's gotta be a better way than throwing away first gear. What you seem to be saying is that you have too much torque on the startline and are willing to give up TM(Torque Multiplication) to take off slower/easier; the exact opposite of most streeters!
You are talking about a 40% reduction in TM. That is an awful lot of TM to completely give up at a time that really really counts; when it seems just a few milliseconds of power-delay, might accomplish a similar result. But what do I know, I ain't no racer, and I'm sure you already thought of that ....... lol.
Decisions, decisions so many decisions. I'd hate to be in your shoes,lol.
