That is what I do, just run a seperate cable for each orbital slot (individual lnbf for each satellite - one for 110, one for 119, one for 129) connected and having no built in switch lnbf (twins) far away from the satellite keeping all switches at the receivers or right at the house. This tends to work well. DP is supposed to help extend the length of wire you can use so that may be the best thing to use in this case running a wire for each DP lnbf you have connected. Couldn't someone use a DP or legacy twin lnbf then connect one wire on each side to the house then use a switch at the house to combine it there even though it has a switch built in? I ask this because the lnbf acts as two seperate lnbfs until a check switch is done to my knowledge.
