Rulebook says:

two 1.75 x 1.75 x .110" or .75 x 4"min. x .049 CM gussets may be used to replace up to 25% of the weld.

That's for 8.50 and slower. The SFI specs may allow something similar but I couldn't find it in a quick search of the book. Regardless, I would NOT do one like this. Nor would I touch something that the design of was not safe and proper IMO. That's just me and the OP is within his rights to not compromise his standards to satisfy a customer who's standards are not as strict. It's your name on it.


ETA, boy, I'm a slow typist.
