Since you've mentioned length and wanting to find the goldilocks setup, to be completely honest I've even been messing with the idea of running a 13.7" barrel as an SBR setup (with URX3 10.75"), but the honest answer is that it doesn't make a ton of sense.
The 14.5" is fairly easily justified for a TitleII lower owner wanting a do-all recce, but the 12.5" can still do a lot in that regard too, it's more of a case where the difference between a shorter than 3' long gun and longer than 3' long gun is unusually huge, especially when some of the densest handling part is dangling off the muzzle (in an inch and a half wide cylinder), so tucking that even even am measly 2" can really do a lot.
As far as handguard, if you're already happy running the Troy's Never run a troy. My quad rail weighs nearly the same, so no need for a tube., the KMR will fill that role just as well, being extremely light, with the BCM mini-VFG and some key-mod panels, you'll be more than adequately isolated thermally if you have a bunch of plastic around there - iirc the KAC cover is probably the best candidate for that. I've always felt that lighter longer guns handle like shorter ones, so little stuff like running a 3V Scout and KMR rail can make it an easier rifle to run - same idea with the offset KAC sights - that means you can run a much lighter (if you like that height over bore, the API super-light might be the best option) fixed scope mount without losing and effectiveness. Agreed. I am thinking that the M300U is a good idea.
Don't get Gunz started on the source of the BCM barrels, but right now you can source really high quality barrels from plenty of sources, including BCM/DD/Centurion/Noveske, in both 12.5" and 14.5" flavors, so if the 14.5" covers that area you want for compromise performance, go with that and drive on.
The only reason we're looking at you a bit funny on wanting a Recce type SBR upper is that you've already got a 14.5" unit (I'm assuming a lighter barrel), I don't. so how different do you want the recce one to be (or rather, how similar do you want this one to be). The same argument, if your existing 14.5" is a lighter rifle, why not set this one up to run exclusively as a high performance suppressed only setup (and run a brake on it) then set up your other 14.5" as the training/practice/unsupressed focused rifle, configure them identically, and take advantage of the fact that you have two very similar awesome optics. I've got the ghetto version of this for my go-to rifle pair (a 16" Recce with heavy barrel and 1-6x optic, then a 16" Lightweight with TR24RT or AP T-1 that is the training analog for both the recce and my dual stamp SBR in those two configurations).
