2700K? 
Closest thing I have is some LH351B 3000K CRI90+ emitters from AEDe's LH351D 4000K CRI90+ groupbuys thread, tested by maukka here with a small OP reflector from a Reylight Pineapple:
That is CRI and and tint, here's a bit of an output test:
I also have a brand new spare low-mid-high 3A MOSFET linear driver from FastTech which could work for it. Also have the stock S2+ SMO reflector.
Let me know if this fits. For warmer emitters, take a look at Clemence shop.
Cheers and best regards :-)
