Opinion? Yes. I think it is very odd. Besides, most of the Pesukim given in the Siddurim are Brachos and Shevachim.
About multiple names, while we surely use them differently than the way it was back then, the Minhag is to say two separate Psukim. This is probably because, although they do combine to make up one name, they are after all two separate parts. People often enough name only partly after someone, or add a name.
The B’nei Yissaschar was famously named partly after his uncle, who said it will have a partial effect.
