There are no plans for this at present. Sorry.

I guess this defeats what you were trying to accomplish, but does this
answer your needs? https://play.golang.com/p/5kPX8F_u24l

Thank you. Are there plans to add a type constraint which would allow this?
Maybe something like this?
func slice[From implements To, To any](from []From) []To { ... }

Is it possible to write a generic function which converts a slice of a
concrete type to a slice of an interface that type implements? Something
like this...
// generic version of []*x -> []X (does not compile)
func gslice[From interface{ ~To }, To any](from []From) []To {
var to []To
