2016~2023 Possible CX-9 Lowering Spring Option?

I've been toying with the idea of swapping in a set of 2nd gen CX-5 springs but couldn't find a good set for a good price to try.

Things I've considered...
1) CX-9s are roughly 600lb heavier than CX-5s so theorically 150lb/corner heavier which should squat a fair amount.

2) Strut towers, strut bearings, spring seats are all interchangeable between CX-9 & CX-5 meaning springs should be "plug n play".

Things I would like to know if someone can help...

1) spring length compressed and uncompressed

2) spring rates

Hope this will spark interest for someone who can make this a reality.
