You could use a DiSEqC switch or a 22 kHz tone switch to select the LNB output as well but in that case you would probably need to program two satellites into the receiver, one that would receive only the vertical transponders and the other that would only receive the horizontal transponders. So a 13/18v multi-switch would be much more desirable but the ones I have seen online except for the one in the next paragraph are intended for use with up to four receivers (for use with certain types of Dish Network or DirecTV dishes and LNB's) and I am not certain if you can power both sides of the LNB from a single receiver. Perhaps someone else could address that. I used to have a dish like that set up with a 22 kHz tone switch but I did have to put the H and V sides in my receiver as if they were separate satellites, otherwise there was no way to select the correct polarity.
If you only want to use one wire from the dish to your receiver then you could probably strap something like this to the dish pole but I don't know of anyplace in the USA that sells them, and you'd still want to put a waterproof cap over the unused output. But at least it's not as big as the ones meant to feed four receivers:

Strangely I have found that the original LNB, assuming it still works at all, often works as well as or better than a newer model on those dishes. But another option is to replace the original LNB with a voltage switched one, such as one of these:

Unfortunately the shipping charge on those is rather excessive IMHO, don't know if that's because it's coming from Canada or because the seller wants to make a few extra bucks that he's not paying eBay a commission on. I would have probably purchased one or two some time back to get a couple old Primestar dishes I have working again if the shipping charge didn't seem so unreasonable. You can also use a regular Ku LNB but you'll need to figure out how to attach it to the dish arm and I think that with some other brands you can't get the focal depth set correctly, so any signal gain you get from having a newer LNB is cancelled out by not being able to set the focal depth to the precise optimum distance from the center of the dish, at least not without more mechanical skills than I possess.
