Very good thinking.
Sourcing suitable short wheelbase bogies shouldn’t be a problem - with the double footboards hiding them, the “two-foot rule” may be liberally applied.
Many of the CBSCR “shorties” Mayner mentions were culled in early CIE days, but sat about for years in that museum graveyard that was Albert Quay. They were replaced by (I think five) ancient GSWR bogies of 35-40ft long, for excursions on the T & C. These feature in many pics at Courtmacsherry, even behind “C” class diesels, or double-headed 90 + 100.
These yokes, being ex-GSWR, are even MORE suitable for the Hattons stock, as the GSWR is by a very long way the closest design to them!
Latterly, with Cork’s inevitable sense of independence (!), they were in a non-standard livery - all-over DARK green, with no lining or snails, just a number. This seems to have been a Republic of Glanmire application to secondary stock, boy, as some ex-CBSC stock was similarly treated, boy.
