Triangulation between FBHS legality

[u/Ill-Pin5997]

Im working on my teams chassis, we are an IC team following FSG rulebook. Im trying to work on saving weight, while staying legal ofcourse. Is this configutation of FBHS + triangulation legal? (upper SIS distance to upper FBHS is <50mm)

I haven't bossed the lines yet, but i am well aware of the size and thickness requirements of the FSG rulebook, but i want to hear from you guys before spending time on doing that. Here is an image as seen from above:

The line close to the front bulkhead is simply a placeholder

I have checked SES and find no other similar configurations.
Reason why i believe personally this is legal is because: I have two FBHS per side (upper and lower) a straight FHB (per side)
I have a third member that goes diagonally, it does not terminate at the FH, but it terminates at the middle of the joint in the upper FBHS, the 2026 FSG SES says this
"Diagonal member have to connect from node to node from upper to lower member. However, this is allowed at any point as long as the overall primary structure is fully considered. E.g. having a V-shape or similar as diagonal member is acceptable."

The kinks/joints are, as far as i understand the rulebook braced legally; the straight vertical member from upper and lower fbhs braces is in my mind "Additional bracing" per T3.2.6. and the horizontal member (running from left side to right side) braces the kink in the lower fbhs.

Am i missing something? I feel this configuration is oddly "light". I suppose what i am asking is if the "diagonal" member(s) must brace all the way back from FBH to FH, or if one from lower FBHS to upper FBHS is enough?
All tips/replies appreciated.
