Modifying old Grafar/ Union mills's locomotive

[Le Night ferry]

I want to announce Mr. Koh Yoshimura's processing photo of old Grafar's Clan line and Union Mills's J27.
He milled down molded pipe and atrached new brass pipe.
I found it few years ago, but how do you think about it?

Seems like he mainly uses his own made decal.
I have some old Farish locos, so going to remake Blue Canadian Pacific somedays...
Is it worth to make Rebuilt WC/BoB via cutting Farish's MN?

Also, I inherited Grafar's class 43 from my father.
Did someone modified it like adding lights or repainting it?
