Nice bit of work there, and some great pictures.
I have a similarly sized Fowler Tank Engine in my "to chip" pile, may be a similar situation !
I make things more 'challenging' for myself by fitting sound and stay alives to all my locos. That requires a degree of ingenuity in most cases (particularly older locos). The Fairburn had a speaker and HM7K decoders stuffed in the smoke box, with a small AEModels stayalive either side of the DCC plug. A standard 8 pin decoder would not fit due to the bulky wiring harness, so I used the Next18 version with a ribbon cable adapter - it just fits!
The Y14 (J15) has everything in the tender, which is very shallow - whatever I tried wouldn't work. I use my own 3D printed speaker enclosure, slightly narrower than the Hornby one so it fits in the centre well of the tender chassis. Even with the tender weight removed and using the smallest stay alive, I couldn't get the top back on. But by removing the rear face of the coal space, the decoder will fit under the plastic coal load, leaving space for the stayalive next to the DCC socket.
As for the Caprotti Black 5, it's a new design and Hornby included a moulded in speaker enclosure, 21 pin decoder leaving acres of space for the stay alive.
Every one is different.
