My suggestions as I was planning a lightweight also (too busy with my bigger birds though):
KBDD Pilots Choice 2.0g
stock HP blades 1,5(?)
HP03s 16,600 = 3.2g
AFAIK this motor bogs a lot on the mcpx. C05 it is.
XP7a = about 1.40g (?)
double FET XP3 0,8g
lowpro stock landing gear (from the FIA canopy)
stock seems flimsier, so lighter?
Stock Canopy = 2.5
built a paper canopy from plastic white glossy film (like transparent sheets) 1,4g
hyperion 250 batteries = 7.995g on avg. Sticker .05g
remove black plastic
reverse mounting the battery to make the plug wire shorter
nice thinking!
MH head
Stock frame with Dylan's frame supports (again kind of wanting the strength addition like solid CF)
Yes
Maybe drill some holes in tail boom mount triangles?
Delete tail fin
straight cables to the tail (no wrap around)
