Personally, I'd keep the Acusport Bisley just becasue they're not comon and just about the nicest handling SA I've ever held. got 5 of those little buggers. I'd sell of the p345 just becasue I'm not big on Ruger autos. I'd proberly sell off the Redhawk also. If you went with a 454, having that DA in 45 Colt would be real redundant and proberly see little use. However, I would definately keep the Bisley even though it would be the easiest to sell.
