I've experimented with using RL 10wt race oil in the past to try and find a lighter pure RL blend and it won't work.
RL 10wt with it's HTHSV of 2.7cP and very low 130 VI is heavier than any dino 5W-20. Your proposed blend will still leave you with efectively a light 0W-30 with an unimpressive 157 VI.
The fact remains that RL doesn't make a true 20wt oil and therefore nothing suitable for any 20wt application.
The best option you have to lighten up the RL 0W-20 is to blend in some Sustina 0W-20. A 50/50 blend will give you a heavy 0W-20 like Amsoil but with a much higher 195 VI.
