If you'd be willing to fool the engine to keep longer at lean-burn, maybe it would worth to try either water injection or just a supplemental injector nozzle right after the throttle-body to avoid going too lean at high load (that was quite usual in my country, especially on turbocharged engines).

I only know because I have been there and done that.
Do not trick your engine into running lean, do it right or pay the price.
That reminds me of some misconceptions held against CNG in my country. Since it has a higher compressibility than gasoline or ethanol, many conversions are set to run so lean on CNG that the engine easily overheats, damaging valve seats or even cracking the engine head.
