Well yeah nick, you’re not really going to get throw from a tiny TIR in a multi optic. Black or White Flat either one… the TIR is just too small. You might decrease the hot spot size, but it’s still going to be rather floody, especially outside where distance gobbles up light.
The light in my Avatar has 8 LH351D, 4 of which are W6 power bin 70 CRI and 4 of which are U6 in 80 CRI, there are also 4 XP-L HD and 4 XP-L HI as well as the center de-domed and sealed SST-40. They all work in unison though. Tint overall is quite pleasing, beam quality is somewhat dependent on power level, quite well suited to walking in the lower modes and dang near a stadium light when fully powered up. 
Yes, I have HD and HI emitters under the same quad optic, a D4S Ledil Angie in fact. Almost went with some Black Flats but they’re just too low powered. Effectively each of the 17 emitters present here are making 1500 lumens. Might be intersting to use separate drivers and a switch panel….
There is a Zanflare light with 4 independently adjustable heads with switches that allow each head to be turned on or off, perhaps different emitters could be used and different angles set up on the heads to create the flood/throw mixture you’re asking about?
Edit: Nick, have a look at the Zanflare F4 HERE
