i m thinking exaclty same about you, strip or board with nichia 5000°k + Osram Square deep-reds should (dimable) should be the perfect combo! i made strip from cutter with those nichia + xqe660 and also nichia 2000k + cree xd16 3500k and will tell you how its work in few month when i will install them
i reallly neeed to get a provider even on alibaba to get those nichia optisolis 5000k 97 cri , do you know where can i buy them?? ( not cutter, im from europe and its realllly tooo expensive the tax from them :'( , the quality is amazing but tooo expensiv tax!)
i found the osram square deep red on mouser :

but not the nichia
can someone help me to find them?
and what about the LUXEON 3535L HE Plus ??? loooks amazing! espacialy the
LUXEON 3535L HE PLUS 4000k 70cri @200lm/w !

Directly from Nichia. Go to their website and search for Nichia Partners in your country. 13-19ct depending on order volumen. Let me ask a friend. Maybe I can give you a link tomorrow.
Those lumileds are pretty good but the 200lm/w is with 65mA or 0,2w. The nice thing is maximum for HE plus diodes is 300mA, that's almost 1w and you would still get ~160-170lm/w. Nice diodes for high powered boards and I believe QB96 use them already.(together with red and deepreds)
I really like the 2200°k/CRI80 spectrum in the CRI80 SPD chart but its unfortunately not mentioned in the performance list.
CRI90 efficiency looks also pretty good. If all the spectrums are available I would mix them to create something special like the tunable Blux Vesta strips. Depends on which spectrums and CRI's are already available.
Nichia's V3F1 is even more efficient at 65mA compared to these lumileds and is also available in CRI70, 80 and 90. Efficiency is comparable to top bin LM301b(240lm/w in 5000°k/CRI80) and typical efficiency should be a tad better(claims Nichia).
Why not use Nichia's most efficient whites(also up to 240lm/w) + Osram's Oslon Square? Would be an almost unbeatable combi efficiency wise and if you mix lets say ⅔ 4000°k/CRI80 and ⅓ deepred you would probably end up with a 3500°k/CRI90 spectrum. Depending on drive current probably up to 3μMol/J doable.
Do you plan to create your own strips or boards?
