Si... all three of these wheelsets are easily converted to 11s. Hex set and 19mm spanner will handle the Eastons, and the Renolds doesn't even require any tools... the end caps just pull off my hand.
The conversion kits will run $80-90 locally through Western or possibly other local bike shops, or can usually be found online for even less... but yes, convertible.
I don't recall if the Eastons require a redish, but I know the Reynolds does not.
Redish, even if necessary, is pretty straightforward.... I personally think it's easier to push a rim over a MM or two than it is to re-true, a lot of times... but that's me. Usually just do like 1/8th turn clockwise on the non-drive nips each and bam - you'll be right there, and still perfectly true.
If this is of any help..
