Possible to build this custom hook?

// single query/mutation
const mutation = useApi((router) => router.admin.product.edit)
const query = useApi((router) => router.public.product.details)
// or multiple hooks for a router
const { editMutation, createMutation } = useApi((router) => router.admin.product)
//         ^
//         | with type error, if tRPC route (e.g. `admin.product.edit`) does not exist

export const useManager = <FormData extends FieldValues>(
    router: keyof AppRouter["admin"],
    dataMode: "create" | "edit"
) => {
    const nextRouter = useRouter()

    function getMutation(): UseTRPCMutationResult<FormData, any, any, any> {
        if (dataMode === "create") {
            // @ts-ignore
            return trpc.admin[router].create.useMutation()
        } else {
            // @ts-ignore
            return trpc.admin[router].edit.useMutation()
        }
    }

    const mutation = getMutation()

    async function submit(data: FormData) {
        return await mutation.mutateAsync(data) as FormData
    }

    // @ts-ignore
    const deleteMutation: UseTRPCMutationResult<FormData, any, any, any> = trpc.admin[router].delete.useMutation()

    async function purge(slug: string) {
        return await deleteMutation.mutateAsync({ slug })
    }

    const isLoading = mutation.isPending || deleteMutation.isPending

    return { submit, isLoading, redirect: nextRouter.push, purge }
}
