I saw that list the other day and it was like 100% BYU guys I think. There was Doman, Gary Crowton, Justin Ena, and one more that escapes me. I actually kind of wish Crowton was the OC at BYU right now. Life coming full circle type of thing. I think it would work.
My singular thought on Doman is that he seems like the type of guy that has a better chance of being a good head coach than a coordinator so I think it would be a decent/good hire if he cobble up a good staff. I don't know what the pedigree is of the typical position coach at Weber or anything, but Doman has a lot connections at the high school level in Utah + the other coaches that BYU fired last year haven't picked up jobs yet so there is potential to put together a good staff.
