I say try out a Pompino if your measurements are similar. That way you know how to make the right changes. There's not much point building something too similar when a pompino is so cheap.
There's a lot of off the peg frames out there that might work. Basically a small version of what you currently have would be much better.
Don't waist your opportunity on a custom until you're sure what you want.
Test how much toe overlap you can get away with too. You might be surprised.
You want to get the front wheel as tight in as possible with a comfortable clearance.
